Presently, pg_upgrade assumes that all non-default tablespaces don't move to different directories during upgrade. Unfortunately, this isn't true for in-place tablespaces, which move to the new cluster's pg_tblspc directory. This commit teaches pg_upgrade to handle in-place tablespaces by retrieving the tablespace directories for both the old and new clusters. In turn, we can relax the prohibition on non-default tablespaces for same-version upgrades, i.e., if all non-default tablespaces are in-place, pg_upgrade may proceed. This change is primarily intended to enable additional pg_upgrade testing with non-default tablespaces, as is done in 006_transfer_modes.pl.
