  1. Add lock statistics 

    Adding a new stat kind PGSTAT_KIND_LOCK for the lock statistics.

This new statistic kind is a fixed one because its key is the lock type
so that we know its size is LOCKTAG_LAST_TYPE + 1.

This statistic kind records the following counters:

requests
waits
timeouts
deadlock_timeouts
deadlocks
fastpath

No extra details is added (like the ones, i.e relation oid, database oid, we
can find in pg_locks). The idea is to provide an idea on what the locking
behaviour looks like.
