WL#4189 mtr.pl v2

- rewrite "check warnings" to be faster by not creating a full join
   between error_log and suspicious_patterns while running REGEXP.
   Instead add a column to error_log that will be set to 1 to indicate
   a warning and run the 6 REGEXP's we have for suspicious lines as
   6 separate full table scans.
 - Remove the "suspicious_patterns" table from mtr db
 - Use 'xykls37' as separator when loading the error log, that line should
   hopefully never exist in a line that should be a warning
