Subject: Remove RelationGetBufferWithBuffer(), which is horribly confused
 about appropriate pin-count manipulation, and instead use
 ReleaseAndReadBuffer. Make use of the fact that the passed-in buffer (if
 there is one) must be pinned to avoid grabbing the bufmgr spinlock when we
 are able to return this same buffer.  Eliminate unnecessary 'previous tuple'
 and 'next tuple' fields of HeapScanDesc and IndexScanDesc, thereby removing a
 whole lot of bookkeeping from heap_getnext() and related routines.
