Pull request description:

55771b7c6a8d4a204c63e70db73a0071c41a0dc4 Removed unused == operator from CMutableTransaction. (lucash.dev@gmail.com)
Pull request description:
This removes the unused == operator from `CMutableTransaction`.
The motivation is that unused code has a cost but offers no benefit (in general), while also adding the risk of introducing silent bugs. On top of that this particular code is quite inefficient, unnecessarily calculating the hash (it could, say, compare serializations). So if anyone ever needs to use a == comparison on `CMutableTransaction`, they'd be better of having to reimplement it (and add tests) than relying on code that's not being maintained.
Note: after this, trying to use the == operator on CMutableTransactions results in a compilation error:
```
./primitives/transaction.h:405:15: error: invalid operands to binary expression ('CMutableTransaction' and
'CMutableTransaction')
```

47776a958b08382d76d69b5df7beed807af168b3 Add linter: Make sure all shell scripts opt out of locale dependence using "export LC_ALL=C" (practicalswift)
3352da8da1243c03fc83ba678d2f5d193bd5a0c2 Add "export LC_ALL=C" to all shell scripts (practicalswift)
Pull request description:
~~Make sure `LC_ALL=C` is set when using `grep` range expressions.~~
Make sure `LC_ALL=C` is set in all shell scripts.
From the `grep(1)` documentation:
> Within a bracket expression, a range expression consists of two characters separated by a hyphen. It matches any single character that sorts between the two characters, inclusive, using the locale's collating sequence and character set. For example, in the default C locale, `[a-d]` is equivalent to `[abcd]`. Many locales sort characters in dictionary order, and in these locales `[a-d]` is typically not equivalent to `[abcd]`; it might be equivalent to `[aBbCcDd]`, for example. To obtain the traditional interpretation of bracket expressions, you can use the C locale by setting the `LC_ALL` environment variable to the value C.

42c499614a Docs: Improve readability of "Squashing commits" (wodry)
Pull request description:
It was not easy to read the comment lines for me because I was not sure whether the sentence ended with the line or not ("pull set commits"?).
Therefore, dots had been invented and I have added them to signal the end of a sentence. Also begin New sentence with a capital letter.
I guess, not all 'pick' words should be replaced by 'squash'? At least I found [this DO](https://www.digitalocean.com/community/tutorials/how-to-rebase-and-update-a-pull-request) rebase/squash documentation helpful, where is written that the first line should not be changed.

9b72c988a0 scripted-diff: Avoid temporary copies when looping over std::map (Ben Woosley)
Pull request description:
The ::value_type of the std::map/std::multimap/std::unordered_map containers is
std::pair<const Key, T>. Dropping the const results in an unnecessary copy,
for example in C++11 range-based loops.
For this I started with a more general scripted diff, then narrowed it down
based on the inspection showing that all actual map/multimap/unordered_map
variables used in loops start with m or have map in the name.

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.

86edf4a2a502416ba8d6cebbce61030992f7ff6f 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.

available options in different binaries
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.

57ba401abcfe564a2c4d259e0f758401ed74616d 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.

e5b2cd8e7564b9fc2ed4f63fe49efb0af60b4460 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

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.

A failure of "lib missing" has limited utility.
