25bc9615b7 Document validationinterace callback blocking deadlock potential. (Matt Corallo)
Pull request description:
From the branches-I've-had-lying-around-and-forgot-to-PR department...
This is a comment-only PR, but the comments point out an API quirk that isn't exactly trivial. None of our use-cases right now hit this, but if we were to call SyncWithValidationInterfaceQueue (eg to limit queue depth) in ATMP, I'm pretty sure we'd hit a deadlock there.

86edf4a2a5 expose CBlockIndex::nTx in getblock(header) (Gregory Sanders)
Pull request description:
Recent publication of a weakness in Bitcoin's merkle tree construction demonstrates many SPV applications vulnerable to an expensive to pull off yet still plausible attack: https://bitslog.wordpress.com/2018/06/09/leaf-node-weakness-in-bitcoin-merkle-tree-design/
Including the coinbase in the txoutproof seems the most effective fix, however results in a significant efficiency downgrade. Transactors will not even know a priori what the size of their proof will be within a couple orders of magnitude, unless they use the mid-state of SHA2 as detailed in the blog post.
Some applications, like Elements blockchain platform that take SPV-style proofs have optional access to a bitcoind to verify these proofs of inclusion and check depth in the chain. Returning `CBlockIndex::nTx` would allow an extremely easy and compact way of checking the depth of the tree, with no additional overhead to the codebase, and works with pruned nodes.
`getblockheader` is arguably not the place for it, but as mentioned before, is a natural workflow for us checking depth of a block in a possibly pruned node.
We should also ensure that `verifytxoutproof` ends up validating this depth fact as well, but left this for another PR.

c2dfbb4a97 Add unavailable options to hidden options category (Andrew Chow)
Pull request description:
From IRC:
```
<ossifrage> FYI, bitcoin-qt from the head I built today won't start if you have "daemon=0" in the config file, so you can't use the same config for either bitcoind or bitcoin-qt
<ossifrage> Seems like bitcoin-qt should ignore this option?
<provoostenator> ossifrage: probably caused by 13112. Another problem is disablewallet=1 will prevent a launch if you compile bitcoind without wallet. It probably needs to be relaxed slightly.
```
Adds all of the options that are unavailable due to compiling options to the hidden category so that shared config files do not break with the alternative binaries.

Options that are not available (but known in the source code) will
cause an error if they are specified.
Make these options "available" by adding them to the hidden options

57ba401abc Enable double-SHA256-for-64-byte code on 32-bit x86 (Pieter Wuille)
Pull request description:
The SSE4 and AVX2 double-SHA256-for-64-byte input code from #13191 compiles fine on 32-bit x86 systems, but the autodetection logic in sha256.cpp doesn't enable it. Fix this.
Note that these instruction sets are only available on CPUs that support 64-bit mode as well, so it is only beneficial in the (perhaps unlikely) scenario where a 64-bit CPU is running a 32-bit Bitcoin Core binary.

e5b2cd8e75 Use python instead of slow shell script on verify-commits (Chun Kuan Lee)
Pull request description:
The cron job that runs every day would fail because of git checkout a single commit, not a branch.
#12708 introduce a method to check whether merges are clean.
However, there are four merges are not clean.
So, I add a list of merges that are dirty and ignore them.
Also, I modify the current shell script to python, it makes the script speed up a lot.
The python code `tree_sha512sum` was copied from `github-merge.py`
I've re-designed this. Now we verify all the things by default.
- Add `--disable-tree-check` option, not to check SHA-512 tree
- Add `--clean-merge NUMBER` option, only verify commits after <NUMBER> days ago

fa7a6cf1b3 policy: Treat segwit as always active (MarcoFalke)
Pull request description:
Now that segwit is active for a long time, there is no need to reject transactions with the reason that segwit hasn't activated.
Strictly speaking, this is a bug fix, because with the release of 0.16, we create segwit transactions in our wallet by default without checking if they are allowed by local policy.
More broadly, this simplifies the code as if "premature witness" was always set to true with the corresponding command line args.

Currently, `TransactionWithinChainLimit` is restricted to single-output use, and needs to be called every time for different limits. If it is replaced with a chain limit value calculator, that can be called once and reused, and is generally more flexible (see e.g. #12257).
Update: this PR now corrects usage of max ancestors / max descendants, including calculating the correct max descendant value, as advertised for the two limits.
~~This change also makes `nMaxAncestors` signed, as the replacement method will return `-1` for "not in the mempool", which is different from "0", which means "no ancestors/descendants in mempool".~~
~~This is a subset of #12257.~~

Instead of combining the -limitancestorcount and -limitdescendantcount into a nMaxChainLength, this commit uses each one separately in the coin eligibility filters.
The chain limits check for max descendants would check the descendants of the transaction itself even though the description for -limitdescendantcount says 'any ancestor'. This commit corrects the descendant count check by finding the top parent transaction in the mempool and comparing against that.
TransactionWithinChainLimits would take a 'limit' and check it against ascendants and descendants. This is changed to take an explicit
max ancestors and max descendants value, and to test the corresponding value against its corresponding max.
