Move InRecovery and standbyState global vars to xlogutils.c.

Browse Source 
They are used in code that runs both during normal operation and during
WAL replay, and needs to behave differently during replay. Move them to
xlogutils.c, because that's where we have other helper functions used by
redo routines.
