The function log_thread_flush() is an exact copy of flush_lgoqueue(), so
both clearly don't need to exist. Also, There is no reason to make all
of the log thread variables global. The only time any of them were
being used outside of log_thread.c, was to reset the log. This code
should never be run if the log_thread isn't running, so it makes more
sense to live inside of log_thread.c
