cf02779 Add logging and error handling for file syncing (Wladimir J. van der Laan)
Pull request description:
Add logging and error handling inside, and outside of FileCommit.
Functions such as fsync, fdatasync will return error in case of hardware I/O errors, and ignoring this means it can silently continue through data corruption.
(c.f. https://lwn.net/SubscriberLink/752063/12b232ab5039efbe/)
EINVAL is handled specially to avoid crashing out on (network, fuse) filesystems that don't handle `f[data]sync`.
I checked that the syncing inside leveldb is already generating an I/O error as appropriate.

Default `-printtoconsole` to false for the GUI. GUI programs should not
print to the console unnecessarily. For example, when launched by the
window manager, the output might end up in the X session log file,
resulting in duplicate logging. On Windows, it is pointless as well
because bitcoin-qt isn't a console application.

6efd964 refactor: Drop CWalletRef typedef (João Barbosa)
Pull request description:
This is a small step towards dynamic wallet load/unload. The wallets *registry* `vpwallets` is used in several places. With these new functions all `vpwallets` usage are removed and `vpwallets` is now a static variable (no external linkage).
The typedef `CWalletRef` is also removed as it is narrowly used.

150b2f0 Default to defining endian-conversion DECLs in compat w/o config (Matt Corallo)
Pull request description:
While this isn't a supported build configuration, some build
systems need to build without going through our autotools steps,
so defaulting to something sane may make it easier to build.
Specifically, this fixes the inability to build
rust-bitcoinconsensus on some non-x86 platforms. It needs to build
without our autotools/configure steps to ensure correct compile
args are passed from the rust build system to gcc. Converting the
args from the rust build system to gcc would be a lot of
unmaintainable work.

c1d742025c [tests] Fix feature_block flakiness (John Newbery)
Pull request description:
feature_block.py occasionally fails on Travis. I believe this is due to
a a race condition when reconnecting to bitcoind after a subtest that
expects disconnection. If the test runs ahead and sends the INV for the
subsequent test before we've received the initial sync getheaders, then
we may end up sending two headers messages - one as a response to the
initial sync getheaders and one in response to the INV getheaders. If
both of those headers fail validation with a DoS score of 50 or higher,
then we'll unexpectedly be disconnected.
There is only one validation failure that has a DoS score bewteen 50 and
100, which is high-hash. That's why the test is failing immediately
after the "Reject a block with invalid work" subtest.
Fix is to wait for the initial getheaders from the peer before we
start populating our blockstore. That way we won't have any invalid
headers to respond to it with.

ce650182f4 Use P2SH consensus rules for all blocks (Suhas Daftuar)
Pull request description:
As discussed at the IRC meeting back in October (https://botbot.me/freenode/bitcoin-core-dev/2017-10-12/?msg=92231929&page=2), I had looked into the feasibility of enforcing P2SH and SCRIPT_VERIFY_WITNESS back to the genesis block.
The P2SH change is pretty straightforward -- there was only one historical block on mainnet that violated the rule, so I carved out an exception to it, similar to the way we have exceptions for the BIP30 violators.
The segwit change is not entirely as clear. The code changes themselves are relatively straightforward: we can just always turn on SCRIPT_VERIFY_WITNESS whenever P2SH is active. However conceptually, this amounts to splitting up BIP141 into two parts, the part that implements new script rules, and the part that handles witness commitments in blocks.
Arguably though the script rules are really defined in BIP 143 anyway, and so this really amounts to backdating BIP 143 -- script rules for v0 segwit outputs -- back to genesis. So maybe conceptually this isn't so bad...
I don't feel strongly about this change in either direction; I started working on it because I was searching for a way to simplify the way we understand and implement the consensus rules around segwit, but I'm not yet sure whether I think this achieves anything toward that goal.

2c084a6 net: Minor accumulated cleanups (Thomas Snider)
Pull request description:
From now-derelict larger changes I had been working on, here are a series of DRY refactors/cleanups. Net loss of 35 lines of code - a small step in the good fight.
In particular I think operator!= should only ever be implemented as a negation of operator==. Lower chance for errors, and removes the possibility of divergent behavior.

b38200459f benchmark: Removed bench/perf.cpp (Thomas Snider)
Pull request description:
Not sure if these should be separate PRs.
First is removal of a platform abstraction for getting cycle counters where possible. Since the benchmarking switch to counting number of iterations over a fixed window instead of counting cycles per iteration, these are unused.
Second is removal of a few methods from the Node interface that seem vestigial from when the concepts of wallet/node were not as clearly separated.

Seems providing at least minimal visibility to the failure is a good practice.
The only remaining ignored state is in LoadExternalBlockFile, where logging
would likely be spammy.

7d8a8cc Avoid launching as admin when NSIS installer ends. (JeremyRand)
Pull request description:
The Bitcoin Core NSIS script runs with elevated privileges. Unfortunately, this means that it launches Bitcoin Core itself with elevated privileges when the user chooses to launch Bitcoin Core at the end of the installation procedure. This PR works around the issue by having `explorer.exe` launch Bitcoin Core. Seems to be a similar approach to what http://nsis.sourceforge.net/ShellExecAsUser_plug-in does, but without a plugin.
I've tested this with Sysinternals Process Explorer on Windows 10 32-bit. I wouldn't expect any differences in behavior on other Windows releases, but if anyone would like to test on other Windows releases, feel free.

This commit finalizes the deprecation of the wallet 'accounts' API by
removing all account arguments and return values.
RPC behaviour is slightly different if the 'accounts' or 'labels' API is
being used. Those behaviour changes are fully documented in the RPC help
text.
All account RPC methods are now deprecated and can only be called if
bitcoind has been started with the -deprecatedrpc=accounts switch.
Affected RPC methods are:
- getaccount
- getaccountaddress
- getaddressesbyaccount
- getreceivedbyaccount
- listaccouts
- listreceivedbyaccount
- move
- setaccount
