[pulseaudio-discuss] [PATCH pavucontrol] mainwindow: Show the availability of the ports and profiles.

[poljar (Damir Jelić)]

From: "poljar (Damir Jelić)" <poljarinho at gmail.com>

If we know if a certain port is available/unavailable, we can print
that out, as a help to the user (and as debugging for ourselves).
A profile is also available/unavailable if all ports which have that
profile is available/unavailable.

Credit goes to David Henningson for the original idea and some of the code.
