MENT-1098 Crash during update on 10.4.17 after upgrade from 10.4.10
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.
