cleanup: fix and generalize handle_manager thread
* provide an argument to the callback
* don't ignore a callback request if it's already present in the queue
* initialize mutex/cond/in_use flag before starting the thread,
in case the first callback queueing request arrives before
handle_manager had time to initialize
* set/check abort_manager under a mutex, otherwise handle_manager
thread might destroy LOCK_manager before stop_handle_manager
released it
* signal COND on queueing a callback, stop cond_wait on callback request
* always start the thread, even if flush_time is 0
* but keep the old behavior in embedded (no replication, no galera)
* style cleanups (e.g. remove volatile for a variable protected by a mutex)
