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