afc32c5eea Fix rebuild-chainstate feature and improve its performance
Previous refactorings broke the ability to rebuild the chainstate by deleting the chainstate
directory, resulting in an incorrect "Incorrect or no genesis block found" error message. Fix
that.

Also, improve the performance of ActivateBestBlockStep by using the skiplist to only discover
a few potential blocks to connect at a time, instead of all blocks forever - as we likely bail
out after connecting a single one anyway.

ad96e7ccd9 Make -reindex cope with out-of-order blocks
Remember out-of-order block headers along with disk positions. This is

341735eb8f Headers-first synchronization
Many changes:
* Do not use 'getblocks', but 'getheaders', and use it to build a headers tree.
* Blocks are fetched in parallel from all available outbound peers, using a
  limited moving window. When one peer stalls the movement of the window, it is
  disconnected.
* No more orphan blocks. At all. We only ever request a block for which we have
  verified the headers, and store it to disk immediately. This means that a
  disk-fill attack would require PoW.
* Require protocol version 31800 for every peer (released in december 2010).
* No more syncnode (we sync from everyone we can, though limited to 1 during
  initial *headers* sync).
* Introduce some extra named constants, comments and asserts.

Trigger -alertnotify if network is upgrading without you
This adds a -regetest-only undocumented (for regression testing only)
command-line option -blockversion=N to set block.nVersion.

Adds to the "has the rest of the network upgraded to a
block.nVersion we don't understand" code so it calls
-alertnotify when 51 of the last 100 blocks are up-version.
But it only alerts once, not with every subsequent new, upversion
block.

And adds a forknotify.py regression test to make sure it works.

Tested using forknotify.py:

Before adding CAlert::Notify, get:
Assertion failed: -alertnotify did not warn of up-version blocks

Before adding code to only alert once:
Assertion failed: -alertnotify excessive warning of up-version blocks

After final code in this pull:
Tests successful

584a358997 Do merkle root and txid duplicates check simultaneously
Move the txid duplicates check into BuildMerkleTree, where it can be done
much more efficiently (without needing to build a full txid set to detect
duplicates).

The previous version (using the std::set<uint256> to detect duplicates) was
also slightly too weak. A block mined with actual duplicate transactions
(which is invalid, due to the inputs of the duplicated transactions being
seen as double spends) would trigger the duplicates logic, resulting in the
block not being stored on disk, and rerequested. This change fixes that by
only triggering in the case of duplicated transactions that can actually
result in an identical merkle root.

058b08c147 Do not keep fully spent but unwritten CCoins entries cached.
Instead of storing CCoins entries directly in CCoinsMap, store a CCoinsCacheEntry
which additionally keeps track of whether a particular entry is:
* dirty: potentially different from its parent view.
* fresh: the parent view is known to not have a non-pruned version.

This allows us to skip non-dirty cache entries when pushing batches of changes up,
and to remove CCoins entries about transactions that are fully spent before the
parent cache learns about them.

c9d1a81ce7 Get rid of CCoinsView's SetCoins and SetBestBlock.
All direct modifications are now done through ModifyCoins, and BatchWrite is
used for pushing batches of queued modifications up, so we don't need the
low-level SetCoins and SetBestBlock anymore in the top-level CCoinsView class.

f28aec014e Use ModifyCoins instead of mutable GetCoins.
Replace the mutable non-copying GetCoins method with a ModifyCoins, which
returns an encapsulated iterator, so we can keep track of concurrent
modifications (as iterators can be invalidated by those) and run cleanup
code after a modification is finished.

This also removes the overloading of the 'GetCoins' name.

Store fewer orphan tx by default, add -maxorphantx option
There is no reason to store thousands of orphan transactions;
normally an orphan's parents will either be broadcast or
mined reasonably quickly.

This pull drops the maximum number of orphans from 10,000 down
to 100, and adds a command-line option (-maxorphantx) that is
just like -maxorphanblocks to override the default.

629d75faac Combine CCoinsViewCache's HaveCoins and const GetCoins into AccessCoins.
The efficient version of CCoinsViewCache::GetCoins only works for known-to-exist
cache entries, requiring a separate HaveCoins call beforehand. This is
inefficient as both perform a hashtable lookup.

Replace the non-mutable GetCoins with AccessCoins, which returns a potentially-NULL
pointer. This also decreases the overloading of GetCoins.

Also replace some copying (inefficient) GetCoins calls with equivalent AccessCoins,
decreasing the copying.

Perform CVerifyDB on pcoinsdbview instead of pcoinsTip
Bypassing the main coins cache allows more thorough checking with the same
memory budget.

This has no effect on performance because everything ends up in the child
cache created by VerifyDB itself.

It has bugged me ever since #4675, which effectively reduced the
number of checked blocks to reduce peak memory usage.

- Pass the coinsview to use as argument to VerifyDB

- This also avoids that the first `pcoinsTip->Flush()` after VerifyDB
  writes a large slew of unchanged coin records back to the database.

ad49c256c3 Split up util.cpp/h
Split up util.cpp/h into:

- string utilities (hex, base32, base64): no internal dependencies, no dependency on boost (apart from foreach)
- money utilities (parsesmoney, formatmoney)
- time utilities (gettime*, sleep, format date):
- and the rest (logging, argument parsing, config file parsing)

The latter is basically the environment and OS handling,
and is stripped of all utility functions, so we may want to
rename it to something else than util.cpp/h for clarity (Matt suggested
osinterface).

Breaks dependency of sha256.cpp on all the things pulled in by util.

ea100c73fa Reduce maximum coinscache size during verification
Due to growing coinsviewcaches, the memory usage with checklevel=3
(and standard settings for dbcache) could be up to 500MiB on a
64-bit system. This is about twice the peak during reindexing,
unnecessarily extending bitcoind's memory envelope.

This commit reduces the maximum total size of the caches used during
verification to just nCoinCacheSize, which should be the limit.

eb0b56b190 Simplify serialize.h's exception handling
Remove the 'state' and 'exceptmask' from serialize.h's stream implementations,
as well as related methods.

As exceptmask always included 'failbit', and setstate was always called with
bits = failbit, all it did was immediately raise an exception. Get rid of
those variables, and replace the setstate with direct exception throwing
(which also removes some dead code).

As a result, good() is never reached after a failure (there are only 2
calls, one of which is in tests), and can just be replaced by !eof().

fail(), clear(n) and exceptions() are just never called. Delete them.

dc942e6f27 Introduce whitelisted peers.
This adds a -whitelist option to specify subnet ranges from which peers
that connect are whitelisted. In addition, there is a -whitebind option
which works like -bind, except peers connecting to it are also
whitelisted (allowing a separate listen port for trusted connections).

Being whitelisted has two effects (for now):
* They are immune to DoS disconnection/banning.
* Transactions they broadcast (which are valid) are always relayed,
  even if they were already in the mempool. This means that a node
  can function as a gateway for a local network, and that rebroadcasts
  from the local network will work as expected.

Whitelisting replaces the magic exemption localhost had for DoS
disconnection (local addresses are still never banned, though), which
implied hidden service connects (from a localhost Tor node) were
incorrectly immune to DoS disconnection as well. This old
behaviour is removed for that reason, but can be restored using
-whitelist=127.0.0.1 or -whitelist=::1 can be specified. -whitebind
is safer to use in case non-trusted localhost connections are expected
(like hidden services).

b33d1f5ee5
Use fee/priority estimates in wallet CreateTransaction
The wallet now uses the mempool fee estimator with a new
command-line option: -txconfirmtarget (default: 1) instead
of using hard-coded fees or priorities.

A new bitcoind that hasn't seen enough transactions to estimate
will fall back to the old hard-coded minimum priority or
transaction fee.

-paytxfee option overrides -txconfirmtarget.

Relaying and mining code isn't changed.

For Qt, the coin control dialog now uses priority estimates to
label transaction priority (instead of hard-coded constants);
unspent outputs were consistently labeled with a much higher
priority than is justified by the free transactions actually
being accepted into blocks.

I did not implement any GUI for setting -txconfirmtarget; I would
suggest getting rid of the "Pay transaction fee" GUI and replace
it with either "target number of confirmations" or maybe
a "faster confirmation <--> lower fee" slider or select box.

d640a3ceab Relay double-spends, subject to anti-DOS
Allows network wallets and other clients to see transactions that respend
a prevout already spent in an unconfirmed transaction in this node's mempool.

Knowledge of an attempted double-spend is of interest to recipients of the
first spend.  In some cases, it will allow these recipients to withhold
goods or services upon being alerted of a double-spend that deprives them
of payment.

As before, respends are not added to the mempool.

Anti-Denial-of-Service-Attack provisions:
 - Use a bloom filter to relay only one respend per mempool prevout
 - Rate-limit respend relays to a default of 100 thousand bytes/minute
 - Define tx2.IsEquivalentTo(tx1): equality when scriptSigs are not considered
 - Do not relay these equivalent transactions

Remove an unused variable declaration in txmempool.cpp.

171ca7745e estimatefee / estimatepriority RPC methods
New RPC methods: return an estimate of the fee (or priority) a
transaction needs to be likely to confirm in a given number of
blocks.

Mike Hearn created the first version of this method for estimating fees.
It works as follows:

For transactions that took 1 to N (I picked N=25) blocks to confirm,
keep N buckets with at most 100 entries in each recording the
fees-per-kilobyte paid by those transactions.

(separate buckets are kept for transactions that confirmed because
they are high-priority)

The buckets are filled as blocks are found, and are saved/restored
in a new fee_estiamtes.dat file in the data directory.

A few variations on Mike's initial scheme:

To estimate the fee needed for a transaction to confirm in X buckets,
all of the samples in all of the buckets are used and a median of
all of the data is used to make the estimate. For example, imagine
25 buckets each containing the full 100 entries. Those 2,500 samples
are sorted, and the estimate of the fee needed to confirm in the very
next block is the 50'th-highest-fee-entry in that sorted list; the
estimate of the fee needed to confirm in the next two blocks is the
150'th-highest-fee-entry, etc.

That algorithm has the nice property that estimates of how much fee
you need to pay to get confirmed in block N will always be greater
than or equal to the estimate for block N+1. It would clearly be wrong
to say "pay 11 uBTC and you'll get confirmed in 3 blocks, but pay
12 uBTC and it will take LONGER".

A single block will not contribute more than 10 entries to any one
bucket, so a single miner and a large block cannot overwhelm
the estimates.

4d79098ad5 Increase IsStandard() scriptSig length
Removes the limits on number of pubkeys for P2SH CHECKMULTISIG outputs.
Previously with the 500 byte scriptSig limit there were odd restrictions
where even a 1-of-12 P2SH could be spent in a standard transaction(1),
yet multisig scriptPubKey's requiring more signatures quickly ran out of
scriptSig space.

From a "stuff-data-in-the-blockchain" point of view not much has changed
as with the prior commit now only allowing the dummy value to be null
the newly allowed scriptSig space can only be used for signatures. In
any case, just using more outputs is trivial and doesn't cost much.

Generally useless information. Only updates on connect time, not after

preventing that.

In the past it was used for progress display in the GUI but
`CheckPoints::guessVerificationProgress` provides a better way that is now used.
It was too easy to mislead it. Peers do lie about it in practice, see issue #4065.

From the RPC, `getpeerinfo` gives the peer raw values, which are more
useful.

f48742c2bf Get rid of C99 PRI?64 usage in source files
Amend to d5f1e72. It turns out that BerkelyDB was including inttypes.h
indirectly, so we cannot fix this with just macros.

Trivial commit: apply the following script to all .cpp and .h files:

    # Middle
    sed -i 's/"PRIx64"/x/g' "$1"
    sed -i 's/"PRIu64"/u/g' "$1"
    sed -i 's/"PRId64"/d/g' "$1"
    # Initial
    sed -i 's/PRIx64"/"x/g' "$1"
    sed -i 's/PRIu64"/"u/g' "$1"
    sed -i 's/PRId64"/"d/g' "$1"
    # Trailing
    sed -i 's/"PRIx64/x"/g' "$1"
    sed -i 's/"PRIu64/u"/g' "$1"
    sed -i 's/"PRId64/d"/g' "$1"

the defines in util.h.

d5f1e727a8 Don't use PRIx64 formatting derives from inttypes.h
As the tinyformat-based formatting system (introduced in b77dfdc) is
type-safe, no special format characters are needed to specify sizes.

Tinyformat can support (ignore) the C99 prefixes such as "ll" but
chokes on MSVC's inttypes.h defines prefixes such as "I64X". So don't
include inttypes.h and define our own for compatibility.

(an alternative would be to sweep the entire codebase using sed -i to
get rid of the size specifiers but this has less diff impact)

2b72d46f42 Handle "conflicted" transactions properly
Extend CMerkleTx::GetDepthInMainChain with the concept of
a "conflicted" transaction-- a transaction generated by the wallet
that is not in the main chain or in the mempool, and, therefore,
will likely never be confirmed.

GetDepthInMainChain() now returns -1 for conflicted transactions
(0 for unconfirmed-but-in-the-mempool, and >1 for confirmed).

This makes getbalance, getbalance '*', and listunspent all agree when there are
mutated transactions in the wallet.

Before:
 listunspent: one 49BTC output
 getbalance: 96 BTC (change counted twice)
 getbalance '*': 46 BTC (spends counted twice)

After: all agree, 49 BTC available to spend.

Keep track of which block is being requested (and to be requested) from

detect stalled downloads, and disconnect if they persist for too long.

75f51f2a63 Prepare block connection logic for headers-first.
This changes the block processing logic from "try to atomically switch
to a new block" to a continuous "(dis)connect a block, aiming for the
assumed best chain".

This means the smallest atomic operations on the chainstate become
individual block connections or disconnections, instead of entire
reorganizations. It may mean that we try to reorganize to one block,
fail, and rereorganize again to the old block. This is slower, but
doesn't require unbounded RAM.

It also means that a ConnectBlock which fails may be no longer called
from the ProcessBlock which knows which node sent it. To deal with that,
a mapBlockSource is kept, and invalid blocks cause asynchronous "reject"
messages and banning (if necessary).

Fix off-by-one errors in use of IsFinalTx()
Previously CreateNewBlock() didn't take into account the fact that
IsFinalTx() without any arguments tests if the transaction is considered
final in the *current* block, when both those functions really needed to
know if the transaction would be final in the *next* block.

Additionally the UI had a similar misunderstanding.

Also adds some basic tests to check that CreateNewBlock() is in fact
mining nLockTime-using transactions correctly.

9b59e3bda8 Sanitize assert usage and refuse to compile with NDEBUG.
There were quite a few places where assert() was used with side effects,
 making operation with NDEBUG non-functional.  This commit fixes all the
 cases I know about, but also adds an  #error on NDEBUG because the code
 is untested without assertions and may still have vulnerabilities if
 used without assert.

98c7c8fd1d Remove dead transaction replacement code
This dead code can be resurrected from git history if
transaction replacement is ever implemented. Keeping
dead code in the source is a bad idea, because it implies
it was tested and worked at some point, which is not true.

6a4c196dd6 Drop fees by 10x due to the persistently higher exchange rate.
The last fee drop was by 5x (from 50k satoshis to 10k satoshis)
in the 0.8.2 release which was about 6 months ago.

The current fee is (assuming a $500 exchange rate) about 5 dollar
cents. The new fee after this patch is 0.5 cents.

Miners who prefer the higher fees are obviously still able to
use the command line flags to override this setting. Miners who
choose to create smaller blocks will select the highest-fee paying
transactions anyway.

This would hopefully be the last manual adjustment ever required
before floating fees become normal.

As block index entries have a flag for marking invalid blocks, the

  check is done in LogPrintf() when category is != NULL (true for all
  LogPrint() calls
- remove fDebug ONLY in code which is NOT performance-critical
- harmonize addrman category name

170e02deaf Generalize the remove-outputs check for fully-prunable transactions.
Instead of explicitly testing for the presence of any output, and
dealing with this case specially, just interpret it as an empty
CCoins.

The case previously caught using the HaveCoins check, is now handled
by the generic outs != outsBlock test.
