config: deprecate ao and vo auto-profiles

These never made any sense. They checked the --vo/--ao option, and
applied the profile corresponding to the first entry. So the only way to
get any use of those was to use the --ao or --vo option explicitly. You
can get the same functionality by making a manual profile, making these
force the ao/vo, and then using --profile on command line instead of
--vo/--ao.
