Log message:
    Create a new HeapTupleSatisfiesVacuum() routine in tqual.c that embodies the
    validity checking rules for VACUUM.  Make some other rearrangements of the
    VACUUM code to allow more code to be shared between full and lazy VACUUM.
    Minor code cleanups and added comments for TransactionId manipulations.
