fa3c910bfe test: Move linters to test/lint, add readme (MarcoFalke)
Pull request description:
This moves the checks and linters from `devtools` to a subfolder in `test`. (Motivated by my opinion that the dev tools are mostly for generating code and updating the repo whereas the linters are read-only checks.)
Also, adds a readme to clarify that checks and linters are only meant to prevent bugs and user facing issues, not merely stylistic preference or inconsistencies. (This is motivated by the diversity in developers and work flows as well as existing code styles. It would be too disruptive to change all existing code to a single style or too burdensome to force all developers to adhere to a single style. Also note that our style guide is changing, so locking in at the wrong style "too early" would only waste resources.)

This adds support for setting the environment variable `BUILDDIR`
to point to executables that are outside the source directory.
E.g. to invoke the tool when the build is in $PWD/build:
```bash
BUILDDIR=$PWD/build contrib/devtools/gen-manpages.sh
```
Three subcommands to this script:
1) ./copyright_header.py report
Examines git-tracked files with extensions that match:
INCLUDE = ['*.h', '*.cpp', '*.cc', '*.c', '*.py']
Helps to:
-> Identify source files without copyright
-> Identify source files added with something other than "The Bitcoin Core
developers" holder so we can be sure it is appropriate
-> Identify unintentional typos in the copyright line
2) ./copyright_header.py update
Replaces fix-copyright-headers.py. It does file editing in native python
rather than subprocessing out to perl as was the case with
fix-copyright-headers.py. It also shares code with the 'report' functions.
3) ./copyright_header.py insert
Inserts a copyright header into a source file with the proper format and
dates.
This is meant to be a direct translation of the bash script,
with the difference that it retrieves the PR title from github,
thus creating pull messages like:
Merge #12345: Expose transaction temperature over RPC
Run this script from the root of the repository to update all translations from transifex.
It will do the following automatically:
- create a transifex configuration file
- fetch all translations
- post-process them into valid and committable format
Add a script to check that the (Linux) executables produced by gitian
only contain allowed gcc, glibc and libstdc++ version symbols. This
makes sure they are still compatible with the minimum supported Linux
distribution versions.
contrib/devtools/fix-copyright-headers.py script to be able to perform this maintenance task with ease during the rest of the year, every year. Modifications to contrib/devtools/README.md to document what fix-copyright-headers.py does.
