Fix pg_upgrade, broken by the xlogid/segno -> 64-bit int refactoring.
The xlogid + segno representation of a particular WAL segment doesn't make much sense in pg_resetxlog anymore, now that we don't use that anywhere else. Use the WAL filename instead, since that's a convenient way to name a particular WAL segment. I did this partially for pg_resetxlog in the original xlogid/segno -> uint64 patch, but I neglected pg_upgrade and the docs. This should now be more complete.
