MDEV-15 Log all sql errors.

        modified for MySQL 5.5. Logger service moved to the
        plugin/sql_errlog directory to be properly used later.

plugin/sql_errlog/sql_errlog.c:
  Fixes for bugs #956427 (SQL_ERROR_LOG plugin produces bogus warnings about sql-error-log-size-limit value) and #956463 (Server crashes if SQL_ERROR_LOG fails to initialize) they're also MDEV-184 and MDEV-183
    
  The sql_error_log_deinit() should be prepared for the logger_file to be NULL.
  The logger_file_size_limit upper limit wasn't properly set.

-/**
-  @file
-  logger service
-
-  Log file with rotation implementation.
-
-  This service implements logging with possible rotation
-  of the log files. Interface intentionally tries to be similar to FILE*
-  related functions.
-
-  So that one can open the log with logger_open(), specifying
-  the limit on the logfile size and the rotations number.
-
-  Then it's possible to write messages to the log with
-  logger_printf or logger_vprintf functions.
-
-  As the size of the logfile grows over the specified limit,
-  it is renamed to 'logfile.1'. The former 'logfile.1' becomes
-  'logfile.2', etc. The file 'logfile.rotations' is removed.
-  That's how the rotation works.
-
-  The rotation can be forced with the logger_rotate() call.
-
-  Finally the log should be closed with logger_close().
-
-@notes:
-  Implementation checks the size of the log file before it starts new
-  printf into it. So the size of the file gets over the limit when it rotates.
-
-  The access is secured with the mutex, so the log is threadsafe.
