Code clean-up.

1. Fix for the crash in debug mode when the .frm is corrupted and SHOW TABLE STATUS is executed.This also fixes to return the error message to comment field in SHOW TABLE STATUS when the .frm is corrupted
2. Test for corrupted .frm and the SHOW TABLE STATUS


sql/sql_show.cc:
  Fix for the crash in debug mode when the .frm is corrupted and SHOW TABLE STATUS is executed
  This also fixes to return the error message to comment field in SHOW TABLE STATUS when the .frm is corrupted
tests/client_test.c:

Fix for mysql_stmt_close(), so that the PHP layer can map it easily to know whether the 'stmt' is really freed, so that they can free their internal stmts

Increased some tests' robustness a bit :
- Added RESET MASTER to all tests who do SHOW BINLOG EVENTS, to make them independent from previous tests.
- Added save_master_pos to these tests to wait for the slave to start before purging its binary logs.


mysql-test/r/rpl_log.result:
  Updated SHOW BINLOG EVENTS's positions as Monty lengthened std_data/words.dat by 500 bytes.
mysql-test/r/rpl_temporary.result:
  Added RESET MASTER to make positions shown by SHOW BINLOG EVENTS independent of any previous test.
mysql-test/r/rpl_user_variables.result:
  Added RESET MASTER to make positions shown by SHOW BINLOG EVENTS independent of any previous test.
mysql-test/t/rpl_log.test:
  Added save_master_pos to wait for the slave to have started before purging its binary logs.
  Otherwise, we could purge before the slave finishes starting, and then the slave could log events implicitly provoked by previous tests.
mysql-test/t/rpl_temporary.test:
  Added RESET MASTER to make positions shown by SHOW BINLOG EVENTS independent of any previous test.
mysql-test/t/rpl_user_variables.test:
  Added RESET MASTER to make positions shown by SHOW BINLOG EVENTS independent of any previous test.
