cc5c3357cf alsactl: add the daemon mode
For the plug-and-play hardware, like USB devices, it may be helpful
to manage the sound state periodically, before the devices are removed.

This change implements new commands 'daemon' and 'rdaemon' to save
the sound state in defined intervals when the sound controls are changed.

The udev rules can notify the daemon using the 'kill' or 'nrestore'
commands to rescan available cards in the system.

b8560a6bbb alsactl init - restore calls also init on failure
The initialization procedure consist from default initialization and
state restoration. When restore fails for a reason or the config file
contains inaccurate information, then init is called.

Also, if something fails (init or restore), a file specified using -r
option can be created with description what failed. It can be useful
when user space decides to notify user to set the sound driver properly.
