WIP - Synchonizing I/O and file open/close/reopen without holding rwlock For async, we will need to protect I/O from open/close/reopen with the operation being completed on a different thread. Because of this, we can't use a pthread_rwlock, so we basically implement our own. This also allows reducing the contentioon for the obj_lock since we actually just lock the fsal_fd we are using. This implementation ALSO acquires temporary share reservations for more operations. The impact of this actually is that instead of share operations blocking on I/O, they may instead fail.
