09dd3fc369 some backends can handle incorrectly ordered midi events.
(that can happen if multiple sources send to the same
ouput port, in particular async midi events)

Needs testing on all platforms.

d991bb10ca add 'available' interface to the AudioBackendInfo
If a backend can be loaded, it does not mean that it can be used;
e.g. weak-linked jack-backend if libjack is not available.

b1da9af8de ALSA|Dummy: ignore port unregistration when engine is stopped
When changing Engine parameters, ardour first stops
the engine and only later when re-etablishing ports
unregisters/re-registers them.

ALSA: silently ignore port unregs and silently accept registrations
Dummy: print a PBD::info message,

when the backend is closed, unregister all ports.

9658b77327 Revert "ALSA backend: separate flags for is-running and should-be-running"
Theoretically one could alter the plugins after a delivery even on a
frozen track. ..or even change settings, the ordering and add/remove
plugins after the frozen part of a track.

We won't go there. Frozen is frozen. this API is not needed after all.

This reverts commit 6d89488d64.
