This commit is a preparation for making keybindings configurable.
The hardcoded keys in the switch statements of mixer_widget.c,
textbox.c, proc_files.c and card_select.c have been replaced by
command enums. The command that shall be executed is looked up in
the arrays `mixer_bindings` and `textbox_bindings`.
The channel_mask enum has been made public, since LEFT and RIGHT are
used as command arguments in bindings.c.

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.)

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