message:
  Implementation of MWL#172: Add support for prepared statements to HANDLER READ
  It includes speed optimizations for HANDLER READ by caching as much as possible in HANDLER OPEN
  Other things:
  - Added mysqld option --disable-thr-alarm to be able to benchmark things without thr_alarm
  - Changed 'Locked' state to 'System lock' and 'Table lock' (these where used in the code but never shown to end user)
  - Better error message if mysql_install_db.sh fails
  - Moved handler function prototypes to sql_handler.h
  - Remove not anymore used 'thd->locked' member
