We write CALL to binlog; on the opposite we didn't write the
substatements. That choice is necessary because the substatements
may use local vars.
Binlogging should happen when all tables are locked. They are locked
just above, and unlocked by close_thread_tables(). All tables which
are to be updated are locked like with a table-level write lock, and
this also applies to InnoDB (I tested - note that it reduces
InnoDB's concurrency as we don't use row-level locks). So binlogging
below is safe.
Note the limitation: if the SP returned an error, but still did some
updates, we do NOT binlog it. This is because otherwise "permission
denied", "table does not exist" etc would stop the slave quite
often. There is no easy way to know if the SP updated something
(even no_trans_update is not suitable, as it may be a transactional
autocommit update which happened, and no_trans_update covers only
INSERT/UPDATE/LOAD).
