fad0867d6ab9430070aa7d60bf7617a6508e0586 Cleanup -includeconf error message (MarcoFalke)
fa9f711c3746ca3962f15224285a453744cd45b3 Fix crash when parsing command line with -noincludeconf=0 (MarcoFalke)
Pull request description:
The error message has several issues:
* It may crash instead of cleanly shutting down, when `-noincludeconf=0` is passed
* It doesn't quote the value
* It includes an erroneous trailing `\n`
* It is redundantly mentioning `"-includeconf cannot be used from commandline;"` several times, when once should be more than sufficient
Fix all issues by:
* Replacing `get_str()` with `write()` to fix the crash and quoting issue
* Remove the `\n` and only print the first value to fix the other issues
Before:
```
$ ./src/bitcoind -noincludeconf=0
terminate called after throwing an instance of 'std::runtime_error'
what(): JSON value is not a string as expected
Aborted (core dumped)
$ ./src/bitcoind -includeconf='a b' -includeconf=c
Error: Error parsing command line arguments: -includeconf cannot be used from commandline; -includeconf=a b
-includeconf cannot be used from commandline; -includeconf=c
```
After:
```
$ ./src/bitcoind -noincludeconf=0
Error: Error parsing command line arguments: -includeconf cannot be used from commandline; -includeconf=true
$ ./src/bitcoind -includeconf='a b' -includeconf=c
Error: Error parsing command line arguments: -includeconf cannot be used from commandline; -includeconf="a b"
```

247d5740d2 Ignore unknown config file options for now (Pieter Wuille)
04ce0d88ca Report when unknown config file options are ignored (Pieter Wuille)
Pull request description:
As reported by @satwo on IRC a few days ago, the current mechanism of treating unknown config file options as errors is problematic for options like `-rpcclienttimeout` which aren't defined for `bitcoind`.
A full solution would be to either make all binaries be aware of each other's options, or to permit config file options that only apply to specific binaries (`bitcoind`, `bitcoin-qt`, `bitcoin-cli`). Both of these seem too invasive to introduce for 0.17.
As a compromise, this PR makes it ignores those options, but still warn about it in the log file.

fa4760fbb3f1099dcd3c43ebc53c2a761a2170e8 qa: Increase includeconf test coverage (MarcoFalke)
Pull request description:
This adds some missing `return false` for error conditions and adds test coverage [1] for those.
Also, extend recursion warning when the chain was set in one of the includeconfs.
[1] See the red lines in https://marcofalke.github.io/btc_cov/total.coverage/src/util.cpp.gcov.html for missing coverage.

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.

629ff8c -includeconf=<path> support in config handler, for including external configuration files (Karl-Johan Alm)
Pull request description:
Fixes: #10071.
Done:
- adds `-includeconf=<path>`, where `<path>` is relative to `datadir` or to the path of the file being read, if in a file
- protects against circular includes
- updates help docs
~~~Thoughts:~~~
- ~~~I am not sure how to test this in a neat manner. Feedback on this would be nice. Will dig/think though.~~~
