2495110012fc0cb7142a4536791dd79da5cc3e44 test: add coverage for -rpcwallet cli option (Jon Atack)
Pull request description:
The bitcoin-cli `-rpcwallet=` option is an essential RPC/CLI option when more than one wallet is loaded (see `bitcoin-cli -help | grep -A5 rpcwallet` or `src/bitcoin-cli.cpp::L61`) and it currently has no test coverage.
It is not only used by users, but also by the test framework and ~10 test files via `get_wallet_rpc()`.
This PR adds coverage, while simultaneously improving the `-getinfo` coverage when multiple wallets are loaded. This is similar to the test coverage that would be added in #18594.

eb37275a6f972c81caef010b4ee9c5dc88edc759 Fix naming of macOS SDK and clarify version (Andrew Chow)
Pull request description:
Fixes the `MacOSX10.14.sdk.tar.gz` creation command to have `MacOSX.sdk` be correctly named as `MacOSX10.14.sdk` and for the resulting file to be placed in the current directory. Gitian requires that `tar.gz` contains a folder named `MacOSX10.14.sdk` and the command did not do this originally. Having the file be placed in the current directory is a convenience so builders don't have to go find it.
Also clarifies which version of Xcode to download and where it can be downloaded.

9f5608c2893f89cd56c7c548b748996199e0da1d test: check for matching object hashes in wait_for_getdata (Danny Lee)
Pull request description:
Previously, `wait_for_getdata` only looked for the presence of a recent `"getdata"` message. Additionally checking the object hashes inside the message should make tests involving `wait_for_getdata` more robust.
`p2p_sendheaders.py` already overrides `wait_for_getdata` do this check; we can use the same approach consistently across all tests that call `wait_for_getdata`.
This PR is progress towards #18614 , but closing that issue would also involve some additional changes to `wait_for_getheaders`.

fa60afc4fb957875bab1c8982d9d9e4999a3814c wallet: Add BlockUntilSyncedToCurrentChain to dumpwallet (MarcoFalke)
Pull request description:
dumpwallet includes the block hash in the output, so this method depends on the chainstate. According to the developer notes e84a5f0004/doc/developer-notes.md (L1095) it must include a `BlockUntilSyncedToCurrentChain`.
This is a minor fix and does not need backport, I think.
It fixes test failures such as https://travis-ci.org/github/bitcoin/bitcoin/jobs/675487097#L2657 , which can only happen in master because the test was not backported.

fab117096446ab63d1f38c1ef6edbc94a5d4ab52 bench: Remove requirement that all benches use RegTestingSetup (MarcoFalke)
Pull request description:
The benches have always set up one global testing setup. This makes it hard to pick no testing setup at all or one with different params.
Fix this by removing any global state setup from the main `bench.cpp` and leave the setup to each individual bench.
One reason to have one global testing setup is to set the datadir location to a tempdir to avoid reading or writing in the default datadir location. But #13687 should prevent this already.

850847309458f43fc7ce6c13fa08c86e1cae042a Avoid non-trivial global constants in SHA-NI code (Pieter Wuille)
Pull request description:
This is a potential solution for #18456.
It seems that the compiler cannot turn `_mm_set_epi64x(<constant>,<constnant>)` into a constant itself, and thus emits a global initializer for the `MASK`, `INIT0`, and `INIT1` global constants in the sha-ni SHA256 implementation.
Change this by turning them into dumb byte arrays, loading them into an SSE variable whenever needed.
Tested on a SHA-NI capable machine. I do not observe any obvious performance impact (but this is hard to measure, it's already very fast...).

20a30922fbf6ba14e250ca649239af115dbbe7b0 doc: note why we can't use thread_local with glibc back compat (fanquake)
Pull request description:
Given that we went through a [gitian build](https://github.com/bitcoin/bitcoin/pull/18681) to remember why this is the case, we might as well make a note of it in configure.ac.
[From #18681](https://github.com/bitcoin/bitcoin/pull/18681#issuecomment-615526634):
Looking at the Linux build log, this has failed with:
```bash

```
`__cxa_thread_atexit_impl` is used for [thread_local variable destruction](https://sourceware.org/glibc/wiki/Destructor%20support%20for%20thread_local%20variables):
> To implement this support, glibc defines __cxa_thread_atexit_impl exclusively for use by libstdc++ (which has the __cxa_thread_atexit to wrap around it), that registers destructors for thread_local variables in a list. Upon thread or process exit, the destructors are called in reverse order in which they were added.
As suggested, this only became available in glibc 2.18. From the [2.18 release notes](https://sourceware.org/legacy-ml/libc-alpha/2013-08/msg00160.html):
> * Add support for calling C++11 thread_local object destructors on thread
and program exit. This needs compiler support for offloading C++11
destructor calls to glibc.
