Asterisk 16.1.0 in experimental - testing required!

[Bernhard Schmidt]

Hello everyone,

FYI, Asterisk 16.1.0 is now in experimental. It's behaving well on my
test test system and the testsuite is passing, that's all I can say.
Overall I have a slightly better feeling about this version than keeping
the old versions or updating pjproject seperately.

There are still a few packaging things to deal with, but it should work.
Please give it a go, if we want to get this into buster we gonna move fast.

Bernhard
