Make midnam test suite pass again.
The Ardour test suite does not pass. I commented out old crossfade stuff, but
I am not familiar enough with the parts that fail to fix it. It might be a
good idea for someone to look into this. Ideally we'd have the test integrated
into everyone's workflow, but they add quite a few files to compile...
