Add error codes to some PANIC/FATAL errors reports
This adds errcodes to a set of PANIC and FATAL errors in xlog.c and relcache.c, which previously had no errcode at all set, in order to make fleetwide analysis of errorlogs easier. There are many more ereport/elogs left which could benefit from having an errcode but this at least makes a dent in the issue.
