Log message:
	Further work on connecting the free space map (which is still just a
	stub) into the rest of the system.  Adopt a cleaner approach to preventing
	deadlock in concurrent heap_updates: allow RelationGetBufferForTuple to
	select any page of the rel, and put the onus on it to lock both buffers
	in a consistent order.  Remove no-longer-needed isExtend hack from
	API of ReleaseAndReadBuffer.
