When we get a notification that an element has been removed, we have to
recreate our internal control representation to avoid accessing freed
memory. (And the checking for SND_CTL_EVENT_MASK_REMOVE should actually
be done correctly while we're at it.)

A lot of reports that alsamixer crashes in X terminal when the PulseAudio
CTL plugin is activated were entered to the tracking systems.
I figured that there is a linking clash for the shutdown() function.
The shutdown() function in glibc is socket related, but the alsamixer code
redefines this function and appearently that under some linking
circumstances - which PA client invokes during the runtime dynamic linking
- the wrong function is called.
This patch, for safety, renames the shutdown() function from alsamixer
to app_shutdown(), but it might make sense to figure the real linking
culprit to avoid future surprises.

For multichannel mixer controls, add the channel name to each screen
control.
Also make some other small changes.
