[FFe] Upgrade Ardour to 6.6+git for gcc 10 + glib 2.68 compatibility

[Erich Eickmeyer]

Ardour 6.5 currently FTBFS against glib 2.68 and its RCs. Per [1], this failure was introduced as a regression against glib 2.67.5 causing a complete failure to build from source. We were not made aware of this regression until Matthias Klouse (doko) did the mass test rebuild in the hours leading up to Beta Freeze.

After working with the Ardour developers, namely Dr. Robin Gareus, we determined this failure to be solved in Ardour 6.6's git master (soon to be Ardour 6.7) with a minor patch. Unfortunately, since Ardour 6.6 introduces several new features, this is requiring a Feature Freeze Exception to introduce the relevant fixes which were added after 6.6's release.

The only flavor of Ubuntu currently seeding Ardour is Ubuntu Studio. As the Ubuntu Studio lead, I give my approval for this exception.

This package update has been uploaded awaiting approval.

List of changes is available in [2].

Ok, this is really quite a lot of changes, but since this has been +1'ed by the Ubuntu Studio lead (and being only seeded there), I guess let's do it. Hopefully this won't slow the Beta down! If it does, I'll be angry! FFe approved.
