Thread: pgsql: Move pg_wal_replay_wait() to xlogfuncs.c

Move pg_wal_replay_wait() to xlogfuncs.c

This commit moves pg_wal_replay_wait() procedure to be a neighbor of
WAL-related functions in xlogfuncs.c.  The implementation of LSN waiting
continues to reside in the same place.

By proposal from Michael Paquier.
