sound: Fix output/output bars not following external changes
When looking up a bar for a particular stream, special-case the input
and output bars/streams, as they will not be added to the "bars"
hashtable (which is, as per comment, only for applications and the sound
events bar).
Revert "sound: Fix the main volume bars to correctly display changes in volume"
This results in crashes when switching inputs or outputs, as other parts
of the code expect only application bars being added to that hashtable.
The bar was destroyed when switching outputs (as the stream is removed before
a new one being added) but with the bar pointing to freed memory.
This reverts commit 22fa7f1292922621ab6099019f810c2b0a621c99.

wacom: Allow button mapping if the stylus has one button too
The airbrush tool has only one button, and the button mapping combo box
does not work.
We should not bail out if the widget has been removed, that means that
the stylus does not support the second button.
Check upfront the number of buttons to know if the top button parameter
is available.
sound: use row-activated to listen to alert sound changes
We currently install two signal handlers for button-press-event and
selection-changed. As the former also calls the latter, the two interact
in non-obvious ways that can lead to two alerts being played at the same
time under certain circumstances.
Avoid this problem by setting activate-on-single-click on the tree view
and listening to the row-activated signal to drive previews and model
changes.
