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.

Clean up some minor problems exposed by further thought about Panon's bug report on old-style functions invoked by RI triggers. We had a number of other places that were being sloppy about which memory context FmgrInfo subsidiary data will be allocated in. Turns out none of them actually cause a problem in 7.1, but this is for arcane reasons such as the fact that old-style triggers aren't supported anyway. To avoid getting burnt later, I've restructured the trigger support so that we don't keep trigger FmgrInfo structs in relcache memory. Some other related cleanups too: it's not really necessary to call fmgr_info at all while setting up the index support info in relcache entries, because those ScanKeyEntry structs are never used to invoke the functions. This should speed up relcache initialization a tiny bit.

Rearrange fmgr.c and relcache so that it's possible to keep FmgrInfo lookup info in the relcache for index access method support functions. This makes a huge difference for dynamically loaded support functions, and should save a few cycles even for built-in ones. Also tweak dfmgr.c so that load_external_function is called only once, not twice, when doing fmgr_info for a dynamically loaded function. All per performance gripe from Teodor Sigaev, 5-Oct-01.
