MUTEXES in replication:
LOCK_active_mi: this is meant for multimaster, when we can switch from a
master to another. It protects active_mi. We don't care of it for the moment,
as active_mi never moves (it's created at startup and deleted at shutdown, and
not changed: it always points to the same MASTER_INFO struct), because we
don't have multimaster. So for the moment, mi does not move, and mi->rli does
not either.
LOCK_active_mi: [note: this was originally meant for multimaster, to switch
from a master to another, to protect active_mi] It is used to SERIALIZE ALL
administrative commands of replication: START SLAVE, STOP SLAVE, CHANGE
MASTER, RESET SLAVE, end_slave() (when mysqld stops) [init_slave() does not
need it it's called early]. Any of these commands holds the mutex from the
start till the end. This thus protects us against a handful of deadlocks
(consider start_slave_thread() which, when starting the I/O thread, releases
mi->run_lock, keeps rli->run_lock, and tries to re-acquire mi->run_lock).
Currently active_mi never moves (it's created at startup and deleted at
shutdown, and not changed: it always points to the same MASTER_INFO struct),
because we don't have multimaster. So for the moment, mi does not move, and
mi->rli does not either.
