Log message:
    This patch wraps all accesses to t_xmin, t_cmin, t_xmax, and t_cmax in
    HeapTupleHeaderData in setter and getter macros called
    HeapTupleHeaderGetXmin, HeapTupleHeaderSetXmin etc.

    It also introduces a "virtual" field xvac by defining
    HeapTupleHeaderGetXvac and HeapTupleHeaderSetXvac.  Xvac is used by
    VACUUM, in fact it is stored in t_cmin.
