OK, updated to expressly submit LOCK TABLE sl_event_lock, rather than allowing
race condition by doing it inside a stored function.

There a few more places to adjust, as there are stored functions that generate
events:

a) failednode2() generates an event, so the table needs to be locked before
calling this function in src/slonik/slonik.c

b) failoverSet_int() generates an event, hence src/slon/remote_worker.c needs
to lock the table first.

It has been speculated that there's an event created as part of subscription
that needs to be guarded; I still need to seek that out, if it exists.
