fc68ed656f 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,

dbcc1f1d39 Rename PBD::find_file_in_search_path to just PBD::find_file 
saves a bit of typing and not necessary if you look at how it is used.

a79273f681 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.
