e4daecda0b Reimplement CBlockLocator's chain-related logic in CChain.
This removes a few unused CBlockLocator methods, and moves the
construction and fork-finding logic to CChain (which can do these
more efficiently, as it has a height-indexable chain available).
It also makes CBlockLocator independent from the validation code.

971bb3e Added ping time measurement. New RPC "ping" command to request ping. Implemented "pong" message handler. New "pingtime" field in getpeerinfo, to provide results to user. New "pingwait" field, to show pings still in flight, to better see newly lagging peers. (Josh Lehan)

d78900cc1b fix some cosmetic glitches in the codebase
- rename URL into URI in paymentserver where correct
- add some missing Qt-coding-stuff in paymentserver
- change QSpinBox to QLineEdit as base for BitcoinAmountField in .ui files
  (as this is the result when converting the BAF back into base)
- remove some c_str() and replace with QString::fromStdString()
- remove several new-lines
- remove unneeded spaces
- indentation fixes

f8b7aa8625 Longer term workaround for chainstate corruption from negative versions.
This also makes negative transaction versions non-standard.

This avoids an issue triggered in block 256818 where transactions with
negative version numbers were incorrectly serialized into the UTXO set.

On restart nodes detect the inconsistency and refuse to start so long as
a block with these transactions is inside the self-consistency check
window, logging "coin database inconsistencies found". The software
recommends reindexing, but reindexing does not correct the problem.

This should be fixed by changing the chainstate serialization, but
working around it seems harmless for now because the version is not
used by any network rule currently.

A patch free workaround is to start with -checklevel=2 which skips
the consistency checks, but the IsStandard change is important for
miners in order to protect unpatched nodes.

9d14e689c8 [raw] reject insanely high fees by default in sendrawtransaction
There have been several incidents where mainnet experimentation with
 raw transactions  resulted in insane fees.  This is hard to prevent
 in the raw transaction api because the inputs may not be known.
 Since sending doesn't work if the inputs aren't known, we can catch
 it there.

This rejects fees > than 10000 * nMinRelayTxFee or 1 BTC with the
 defaults and can be overridden with a bool at the rpc.

bf3a20a6e8 [wallet] Consider generated coins mature at COINBASE_MATURITY+1
We're not seeing large reorgs that would justify waiting a large
 amount past the rule required maturity, and the extra three
 hours is just a nuisance. Take one more block to at least give
 the 100th block time to propagate.

a7f533a972 Update the bloom state on the real object, not the temporary one.
This resulted in just passing all transactions to filtered wallets
which worked surprisingly well, except where it didn't.

37c6389c5a Performance optimization for bloom filters.
This reduces a peer's ability to attack network resources by
 using a full bloom filter, but without reducing the usability
 of bloom filters.  It sets a default match everything filter
 for peers and it generalizes a prior optimization to
 cover more cases.

159bc48193 Simplify storage of orphan transactions
Orphan transactions were stored as a CDataStream pointer;
this changes the mapOrphanTransactions data structures to
store orphans as a CTransaction.

This also fixes CVE-2013-4627 by always re-serializing
transactions before relaying them.
