If multiple threads are invoking ActivateBestChain, it was possible to have
them working towards different tips, and we could arrive at a less work tip
than we should. Fix this by introducing a ChainState lock which must
be held for the entire duration of ActivateBestChain to enforce
exclusion in ABC.
Technically, some internal datastructures may be in an inconsistent
state if we do this, though there are no known bugs there. Still,
for future safety, its much better to only unlock cs_main if we've
made progress (not just tried a reorg which may make progress).
364bae5 qa: Pad scriptPubKeys to get minimum sized txs (MarcoFalke)
7485488 Policy to reject extremely small transactions (Johnson Lau)
0f8719b Add transaction tests for constant scriptCode (Johnson Lau)
9dabfe4 Add constant scriptCode policy in non-segwit scripts (Johnson Lau)
Pull request description:
This disables `OP_CODESEPARATOR` in non-segwit scripts (even in an unexecuted branch), and makes a positive `FindAndDelete` result invalid. This ensures that the `scriptCode` serialized in `SignatureHash` is always the same as the script passing to the `EvalScript`.

5d536619ab [tests] Remove 'account' API from wallet functional tests (John Newbery)
Pull request description:
Next step in #12952. Removes all usage of the 'account' API from the wallet functional tests, except:
- rpc_deprecated.py (which specifically tests the `-deprecatedrpc=accounts` command line argument is working properly).
- `wallet_labels.py` (which tests that both the 'label' and 'account' APIs work in V0.17).
'account' API usage for both of those tests can be removed once V0.17 has been branched.
Also excluded is:
- `wallet_importprunedfunds.py` (which fails due to a bitcoind OOM error)

09c6699900 [qa] Handle disconnect_node race (Suhas Daftuar)
Pull request description:
Several tests call disconnect_nodes() on each node-pair in rapid
succession, resulting in a race condition if a node disconnects a peer
in-between the calculation of the nodeid's to disconnect and the
invocation of the disconnectnode rpc call. Handle this.

Since 265d7c44b1, when wait_until() fails,
an error message is logged to the test framework log. This means that if
wait_until() is called inside a try-except with the expectation that it
will fail, a spurious error message is logged.
wait_until() shouldn't be called with the expectation of failure. Fix
that in p2p_segwit.py.

a2f678d Bugfix: the end of a reorged chain is invalid when connect fails (Pieter Wuille)
Pull request description:
Introduced in 4e0eed88ac
When an invalid block is found during a reorg, we know the last of the blocks in the was-to-be-connected chain is invalid, but not necessarily the first. As `vpIndexToConnect` is ordered in decreasing height, the end of the reorg is the front of the vector, and not the back.
This only affected the warning system.

e503671 [Tests] Use LIBC_FATAL_STDERR_=1 in tests (John Newbery)
c22ce8a [Tests] Write stdout/stderr to datadir instead of temp file. (John Newbery)
Pull request description:
**Due to a merge conflict, this is now based on #10267. Please review that PR first!**
Subset of #12379 now that parts of that PR have been merged.
#12362 was only observed when running the functional tests locally because:
- by defatul libc logs to `/dev/tty` instead of stderr
- the functional tests only check for substring inclusion in stderr when we're expecting bitcoind to fail.
This PR tightens our checking of stderr and will cause tests to fail if there is any unexpected message in stderr:
- commit *Write stdout/stderr to datadir instead of temp file* writes stderr to a file in the datadir instead of a temporary file. This helps with debugging in the case of failure.
- commit *Use LIBC_FATAL_STDERR=1 in tests* ensures that libc failures are logged to stderr instead of the terminal.
commit *Assert that bitcoind stdout is empty on shutdown* asserts that stderr is empty on bitcoind shutdown.

By default, libc will print fatal errors to /dev/tty instead of stderr.
Adding the LIBC_FATAL_STDERR_ to the environment variables allows
us to catch libc errors in stderr and test for them.

f30e9be4c1 RPC Docs: gettxout*: clarify bestblock and unspent counts (David A. Harding)
Pull request description:
Expounds on two things I've seen confuse inexperienced users:
- transactions/outputs in `gettxoutsetinfo`: a user thought this was the total number of transactions or outputs ever seen on the chain, whereas it's only the number in the UTXO.
- bestblock in `gettxout`: a user thought this was the block that included the output, not realizing it was the tip of the current best block chain. I also copied this text to `gettxoutsetinfo` for congruency. I skimmed other uses of "bestblock" in the RPC docs and they seemed clear to me.

MSVC fails to compile with the changes made in #10742
The problem is enum types were changed to scoped (`enum class`) but in some places `enum` as an unscoped is used.
This is a very simple fix and I've tested it.
Edit: Had to remove enum altogether - `enum class` doesn't compile on clang.

fad63eb [logging] Don't incorrectly log that REJECT messages are unknown. (John Newbery)
Pull request description:
Reject messages are logged to debug.log if NET debug logging is enabled.
Because of the way the `ProcessMessages()` function is structured,
processing for REJECT messages will also drop through to the default
branch and incorrectly log `Unknown command "reject" from peer-?`. Fix
that by exiting from `ProcessMessages()` early.

Replaces the slow modulo operation with a much faster 32bit multiplication & shift. This works
because the hash should be uniformly distributed between 0 and 2^32-1. This speeds up the benchmark
by a factor of about 1.3:
RollingBloom, 5, 1500000, 3.73733, 4.97569e-07, 4.99002e-07, 4.98372e-07 # before
RollingBloom, 5, 1500000, 2.86842, 3.81630e-07, 3.83730e-07, 3.82473e-07 # FastMod
Be aware that this changes the position of the bits that are toggled, so this should probably
not be used for CBloomFilter which is serialized.
