XLogRecPtrIsInvalid() is inconsistent with the affirmative form of macros used for other datatypes, and leads to awkward double negatives in a few places. This commit introduces XLogRecPtrIsValid(), which allows code to be written more naturally. This patch only adds the new macro. XLogRecPtrIsInvalid() is left in place, and all existing callers remain untouched. This means all supported branches can accept hypothetical bug fixes that use the new macro, and at the same time any code that compiled with the original formulation will continue to silently compile just fine.
