Hmm, this seems to be closely equivalent. Patch attached. I also moved
SysScanDescData from genam.h to relscan.h.

Not really, unless we were to provide something a routine that returns
the current block of a scan. There are a few occurrences of this:
/* must hold a buffer lock to call HeapTupleSatisfiesUpdate */
LockBuffer(scan->rs_cbuf, BUFFER_LOCK_SHARE);
which of course need the definition. Maybe providing it is not a bad
idea, because that kind of coding is used in the backend too.
