Fixed memory leak in DROP DATABASE when using RAID tables (Bug #2882)

BUILD/compile-pentium-debug-max:
  Added --with-raid
configure.in:
  Removed -DFN_NO_CASE_SENCE for Mac OS X as this is not always true
mysql-test/install_test_db.sh:
  Added --skip-warnings
mysql-test/mysql-test-run.sh:
  Fixes to get --gdb and --ddd to work
mysql-test/r/lowercase_table2.result:
  Test for lower_case_table_names=2 and temporary tables
mysql-test/r/lowercase_table3.result:
  Fixed error message
mysql-test/r/multi_update.result:
  Test of behaviour of multi-table-delete and alias
mysql-test/t/lowercase_table2.test:
  Test for lower_case_table_names=2 and temporary tables
mysql-test/t/lowercase_table3.test:
  Fixed error
mysql-test/t/multi_update.test:
  Test of behaviour of multi-table-delete and alias (Bug #2940)
mysys/mf_iocache.c:
  Renamed _flush_io_cache to my_b_flush_io_cache
sql/ha_myisam.cc:
  Added comment
sql/lock.cc:
  Extra debugging
sql/log.cc:
  New parameter to flush_relay_log_info
sql/log_event.cc:
  New parameter to flush_relay_log_info
sql/mf_iocache.cc:
  Removed not used header files
sql/mysqld.cc:
  More debugging info
  Less warnings when run with --skip-warnings
sql/opt_range.cc:
  More debug information
sql/repl_failsafe.cc:
  New parameter to flush_relay_log_info
sql/slave.cc:
  First start SQL thread, then start IO thread. This fixed a raze condition in SLAVE START (Bug #2921)
  Ensure that we have a lock on the IO thread before flushing a relay log file that. The original code could core dump when a relay log rotated.

  New parameter to flush_relay_log_info
sql/sql_base.cc:
  Added warning
sql/sql_handler.cc:
  Indentation fix
sql/sql_repl.cc:
  New parameter to flush_relay_log_info

  Fixed problem with deleting temporary tables when using lower_case_table_names=2. (Bug #2858)

  Fixed comment

  Removed compiler warning

  Fixed usage of unpack_filename
