Rename io_direct to debug_io_direct.
Give the new GUC introduced by d4e71df6 a name that is clearly not
intended for mainstream use quite yet.
Future proposals would drop the prefix only after adding infrastructure
to make it efficient. Having the switch in the tree sooner is good
because it might lead to new discoveries about the hazards awaiting us
on a wide range of systems, but that name was too enticing and could
lead to cross-version confusion in future, per complaints from Noah and
Justin.
