Enable trx boundary detection using regexes

Browse Source 
Transaction boundaries can now be detected using regexes.
All else being equal, it gives a 10% performance improvement
compared to qc-based detection.

In a subsequent change, mysql_client.c will be modified to use
qc_get_trx_type_mask() instead of qc_get_type_mask().

Currently the use of regex matching is turned on using an
environment variable. That will change.
