Remove the extra class hierarchy with classes TC_LOG_queued, TC_LOG_unordered, and TC_LOG_group_commit, folding the code into the TC_LOG_MMAP and TC_LOG_BINLOG classes. In particular TC_LOG_BINLOG is greatly simplified by this, unifying the code path for transactional and non-transactional commit. Remove unnecessary locking of LOCK_log in MYSQL_BIN_LOG::write() (backport of same fix from mysql-5.5).
