44407100ff Replace relevant services logic with a function suite.
Adds HasAllRelevantServices and GetRelevantServices, which check
for NETWORK|WITNESS.

This changes the following:
 * Removes nRelevantServices from CConnman, disconnecting it a bit
   more from protocol-level logic.
 * Replaces our sometimes-connect-to-!WITNESS-nodes logic with
   simply always requiring WITNESS|NETWORK for outbound non-feeler
   connections (feelers still only require NETWORK).
 * This has the added benefit of removing nServicesExpected from
   CNode - instead letting net_processing's VERSION message
   handling simply check HasAllRelevantServices.
 * This implies we believe WITNESS nodes to continue to be a
   significant majority of nodes on the network, but also because
   we cannot sync properly from !WITNESS nodes, it is strange to
   continue using our valuable outbound slots on them.
 * In order to prevent this change from preventing connection to
   -connect= nodes which have !WITNESS, -connect nodes are now
   given the "addnode" flag. This also allows outbound connections
   to !NODE_NETWORK nodes for -connect nodes (which was already true
   of addnodes).
 * Has the (somewhat unintended) consequence of changing one of the
   eviction metrics from the same
   sometimes-connect-to-!WITNESS-nodes metric to requiring
   HasRelevantServices.

This should make NODE_NETWORK_LIMITED much simpler to implement.

Merge #11031: [rpc] deprecate estimatefee
048e0c3e2 [rpc] [tests] Add deprecated RPC test (Cristian Mircea Messel)
d4cdbd6fb [rpc] Deprecate estimatefee RPC (John Newbery)

Pull request description:

  Deprecates estimatefee in v0.16, for final removal in v0.17.

  This commit introduces a phased removal of RPC methods. RPC method is
  disabled by default in version x, but can be enabled by using the
  `-deprecatedrpc=<methodname>` argument. RPC method is removed entirely in version
  (x+1).

  This gives users fair warning that an RPC is to be removed, and time to change client software if necessary. Deprecation warnings in RPC return values or release notes are easily ignored.

  This is a more generic version of the approach I tried to use in #10841, which too late to make it into v0.15.

* This removes block-size-limiting code in favor of GBT clients
  doing the limiting themselves (if at all).
* -blockmaxsize is deprecated and only used to calculate an implied
  blockmaxweight, addressing confusion from multiple users.
* getmininginfo's currentblocksize return value was returning
  garbage values, and has been removed, also removing a
  GetSerializeSize call in some block generation inner loops and
  potentially addressing some performance edge cases.

Pull request description:

  Apologies for the mostly code move only PR. This is a pre-req for both #10740 and #10762

  All wallet component initialization/destruction functions are now in their own `wallet/init.cpp` translation unit and are no longer static functions on the CWallet class. The bitcoin_server also no longer has any knowledge that there are multiple wallets in vpwallet.

  There should be no changes in behavior from this PR.

Pull request description:

  As discussed briefly here: https://botbot.me/freenode/bitcoin-core-dev/2017-02-28/?msg=81712308&page=4

  This adds a hidden command line option for setting `nMinimumChainWork`, which allows us to test this parameter in our functional tests, as well as allowing for niche use cases like syncing nodes that are otherwise disconnected from the network.

  See also #10345, which proposes a new use of `nMinimumChainWork`.

ec6902d0ea rpc: Push down safe mode checks
This contains most of the changes of 10563 "remove safe mode", but doesn't
remove the safe mode yet, but put an `ObserveSafeMode()` check in
individual calls with okSafeMode=false.

This cleans up the ugly "okSafeMode" flag from the dispatch tables,
which is not a concern for the RPC server.

Pull request description:

  This just moves some static wallet fee and init functions out of `wallet/wallet.cpp` and into new `wallet/fees.cpp` and `wallet/init.cpp` source files. There is one commit updating declarations and callers, followed by two MOVEONLY commits actually moving the function bodies.

  This change is desirable because wallet.h/cpp are monolithic and hard to navigate, so pulling things out and grouping together pieces of related functionality should improve the organization.

  Another motivation is the wallet process separation work in https://github.com/bitcoin/bitcoin/pull/10973, where (at least initially) parameter parsing and fee estimation are still done in the main process rather than the wallet process, and having functions that run in different processes scrambled up throughout wallet.cpp is unnecessarily confusing.

Merge #11026: Bugfix: Use testnet RequireStandard for -acceptnonstdtxn default
4aa2508 Bugfix: Use testnet RequireStandard for -acceptnonstdtxn default (Luke Dashjr)

Pull request description:

  Fixes a bug introduced in #8855

  `-acceptnonstdtxn` is a valid option only for testnet/regtest (in Core), and the help message reflects that. Currently, however, it is buggy in two ways:

  1. It uses mainnet to get the default value, which doesn't make sense since the option is never available for mainnet, and the only time the option is available, is when the default is the opposite.
  2. It uses the value of "require standard" directly as the default for "accept non-standard transactions", but these concepts are opposites: a negation must be performed to transform one to the other.

  Note the combination of these bugs results in the correct boolean output, but the logic to get there is completely wrong.

90d4d89 scripted-diff: Use the C++11 keyword nullptr to denote the pointer literal instead of the macro NULL (practicalswift)

Pull request description:

  Since C++11 the macro `NULL` may be:
  * an integer literal with value zero, or
  * a prvalue of type `std::nullptr_t`

  By using the C++11 keyword `nullptr` we are guaranteed a prvalue of type `std::nullptr_t`.

  For a more thorough discussion, see "A name for the null pointer: nullptr" (Sutter &
  Stroustrup), http://www.open-std.org/jtc1/sc22/wg21/docs/papers/2007/n2431.pdf

  With this patch applied there are no `NULL` macro usages left in the repo:

  $ git grep NULL -- "*.cpp" "*.h" | egrep -v '(/univalue/|/secp256k1/|/leveldb/|_NULL|NULLDUMMY|torcontrol.*NULL|NULL cert)' | wc -l
  0
  ```

  The road towards `nullptr` (C++11) is split into two PRs:
  * `NULL` → `nullptr` is handled in PR #10483 (scripted, this PR)
  * `0` → `nullptr` is handled in PR #10645 (manual)

    -reindex and -reindex-chainstate both with comments noting
    calls as no-ops and by adding if guards.

  * Move the writing of fTxIndex to LoadBlockIndex - this fixes a
    bug introduced in d6af06d68a where
    InitBlockIndex was writing to fTxIndex which had not yet been
    checked (because LoadChainTip hadn't yet initialized the
    chainActive, which would otherwise have resulted in
    InitBlockIndex being a NOP), allowing you to modify -txindex
    without reindex, potentially corrupting your chainstate!

  * Rename InitBlockIndex to LoadGenesisBlock, which is now a more
    natural name for it. Also check mapBlockIndex instead of
    chainActive, fixing a bug where we'd write the genesis block out
    on every start.

  * Move LoadGenesisBlock further down in init. This is a more logical
    location for it, as it is after all of the blockindex-related
    loading and checking, but before any of the UTXO-related loading
    and checking.

  * Give LoadChainTip a return value - allowing it to indicate that
    the UTXO DB ran ahead of the block DB. This just provides a nicer
    error message instead of the previous mysterious
    assert(!setBlockIndexCandidates.empty()) error.

  * Calls ActivateBestChain in case we just loaded the genesis
    block in LoadChainTip, avoiding relying on the ActivateBestChain
    in ThreadImport before continuing init process.

  * Move all of the VerifyDB()-related stuff into a -reindex +
    -reindex-chainstate if guard. It couldn't do anything useful
    as chainActive.Tip() would be null at this point anyway.

ff3a21919d Call RewindBlockIndex even if we're about to run -reindex-chainstate
RewindBlockIndex works over both chainActive - disconnecting blocks
from the tip that need witness verification - and mapBlockIndex -
requiring redownload of blocks missing witness data.

It should never have been the case that the second half is skipped
if we're about to run -reindex-chainstate.

b0f32497b8 More user-friendly error message if UTXO DB runs ahead of block DB
This gives LoadChainTip a return value - allowing it to indicate that
the UTXO DB ran ahead of the block DB. This just provides a nicer
error message instead of the previous mysterious
assert(!setBlockIndexCandidates.empty()) error.

This also calls ActivateBestChain in case we just loaded the genesis
block in LoadChainTip, avoiding relying on the ActivateBestChain
in ThreadImport before continuing init process.

Merge #10821: Add SSE4 optimized SHA256
6b8d872 Protect SSE4 code behind a compile-time flag (Pieter Wuille)
fa9be90 Add selftest for SHA256 transform (Pieter Wuille)
c1ccb15 Add SSE4 based SHA256 (Pieter Wuille)
2991c91 Add SHA256 dispatcher (Pieter Wuille)
4d50f38 Support multi-block SHA256 transforms (Pieter Wuille)

Pull request description:

  This adds an SSE4 assembly version of the SHA256 transform by Intel, and uses it at run time if SSE4 instructions are available, and use a fallback C++ implementation otherwise. Nearly every x86_64 CPU supports SSE4. The feature is only enabled when compiled with `--enable-experimental-asm`.

  In order to avoid build dependencies and other complications, the original Intel YASM code was translated to GCC extended asm syntax.

  This gives around a 50% speedup on the SHA256 benchmark for me.

  It is based on an earlier patch by @laanwj, though only includes a single assembly version (for now), and removes the YASM dependency.
