The reason for the crash was that there was not a write lock to
protect against file rotations in the server_audit plugin after an
audit plugin patch to changed audit mutexes to read & write locks.
The fixes are:
* Moving server_audit.c to use read & write locks (which improves
performance).
* Added functionality in file_logger.c to not do file rotations until
it is allowed by the caller (done without any interface changes for
the logging service).
* Move checking of file size limit to server_audit.c and if it is time to
do a rotation change the read lock to a write lock and tell file_logger
that it is now allowed to rotate the log files.
This follows up commit
commit 94a520ddbe and
commit 7c5519c12d.
After these changes, the default test suites on a
cmake -DWITH_UBSAN=ON build no longer fail due to passing
null pointers as parameters that are declared to never be null,
but plenty of other runtime errors remain.

In main.index_merge_myisam we remove the test that was added in
commit a2d24def8c because
it duplicates the test case that was added in
commit 5af12e4635.
Plugin fixed to not lock the LOCK_operations when not active.
Server fixed to lock the LOCK_plugin less - do it once per
thread and then only if a plugin was installed/uninstalled.
