Retire pg_standby.

Browse Source 
pg_standby was useful more than a decade ago, but now it is obsolete.
It has been proposed that we retire it many times.  Now seems like a
good time to finally do it, because "waiting restore commands"
are incompatible with a proposed recovery prefetching feature.
