s3-g_lock: Use dbwrap_record_watch_send/recv
This simplifies the g_lock implementation. The new implementation tries to
acquire a lock. If that fails due to a lock conflict, wait for the g_lock
record to change. Upon change, just try again. The old logic had to cope with
pending records and an ugly hack into ctdb itself. As a bonus, we now get a
really clean async g_lock_lock_send/recv that can asynchronously wait for a
global lock. This would have been almost impossible to do without the
dbwrap_record_watch infrastructure.
