Remove obsolete XLogRecPtr macros
This gets rid of XLByteLT, XLByteLE, XLByteEQ and XLByteAdvance.These were useful for brevity when XLogRecPtrs were split inxlogid/xrecoff; but now that they are simple uint64's, they are justclutter. The only downside to making this change would be ease ofbackporting patches, but that has been negated by other substantivechanges to the involved code anyway. The clarity of simpler expressionsmakes the change worthwhile.Most of the changes are mechanical, but in a couple of places, the patchauthor chose to invert the operator sense, making the code flow morelogical (and more in line with preceding comments).Author: Andres FreundEyeballed by Dimitri Fontaine and Alvaro Herrera
