Introduce a new 'V:' ("Verify") entry to MAINTAINERS. The entry accepts
a test suite command which is proposed to be executed for each
contribution to the subsystem.
Extend scripts/get_maintainer.pl to support retrieving the V: entries
when '--test' option is specified.
Require the entry values to not contain the '@' character, so they could
be distinguished from emails (always) output by get_maintainer.pl. Make
scripts/checkpatch.pl check that they don't.
Update entry ordering in both scripts/checkpatch.pl and
scripts/parse-maintainers.pl.

+Test your changes
+-----------------

+Test the patch to the best of your ability. Check the MAINTAINERS file for the
+subsystem(s) you are changing to see if there are any **V:** entries
+proposing particular test suite commands. E.g.::
+
+ V: tools/testing/kunit/run_checks.py

+Supplying the ``--test`` option to ``scripts/get_maintainer.pl`` adds **V:**

+All commands must be executed from the root of the source tree. Each command
