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.
Adding systemd service for bitcoind, to provide for a simpler
out-of-the-box experience.
Configuration file is /etc/bitcoin/bitcoin.conf. This file is a
copy of the sample configuration file.
The service user 'bitcoin' is added during install. Its homedir
is in '/var/lib/bitcoin'.
bitcoind.service is disabled by default to allow the user to
configure it, before starting it the first time.
On package purge, the 'bitcoin' user as well as its homedir is
left intact, to not accidentally remove a wallet or something of
equal importance. Instead the user is presented with information
on how to perform the cleanup manually, after making sure all
important data has been backed up.
b77b6e2345 MOVEONLY: Move logging code from util.{h,cpp} to new files. (Jim Posen)
Pull request description:
Split out first commit from #12954 to reduce amount of rebasing necessary.
This introduces a cyclic dependency between `logging` and `util` that should be cleaned up in a future PR.

Such outputs can still be watched, and signed for, but they aren't treated as valid payments.
That means they won't cause transactions to appear in listtransactions, their outputs to be
shown under listunspent, or affect balances.
Inside IsMine we care about the distinction between scriptPubKey execution
and P2SH redeemScript execution. The consensus code does not care about this
distinction, and thus SigVersion does not have a field for P2SH. As the IsMine
code will care, it uses a separate enum with more fields.
Only IsMine's internal code needs this, as part of a recursion into P2SH and P2WSH
scripts. The exposed functions always operate on actual scriptPubKeys and not on
redeemScripts or witness scripts.

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.

1bf3f33b46 node: Removed unused wallet-related methods from the Node interface. (Thomas Snider)
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
