When scanning for the end of WAL, pg_resetwal has been maintaining its own internal logic to calculate segment numbers and to parse a WAL segment name for its timeline and segment number. The code claimed for example that XLogFromFileName() cannot be used because it lacks the possibility of specifying a WAL segment size, which is not the case since fc49e24, that has made the WAL segment size configurable at initialization time, extending this routine to do so. Similarly, this switches one segment number calculation to use XLByteToSeg() rather than the same logic present in xlog_internal.h. While on it, switch to TimeLineID in pg_resetwal.c for TLI numbers parsed from segment names, to be more consistent with XLogFromFileName(). The maths are exactly the same, but the code gets simplified.
