Oh, but of course we can't modify XLogReaderState in backbranches to add
the new struct member abortedContrecordPtr (or whatever we end up naming
that.)

I think I'm going to fix this, in backbranches only, by having
xlogreader.c have a global variable, which is going to be used by
ReadRecord instead of accessing the struct member.
