MDEV-4472 Audit-plugin. Server-related part of the task.

     file_logger became the service.
     Data like query_id now are sent to the audit plugin.
     Fix for MDEV-4770 ported from 10.0.
     Fix added for the read_maria_plugin_info().
     Log rotation can be disabled with 'set rotations=0'.
