The state management can run at low priority, add --nice and --sched-idle
options to set the scheduler.

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.

- store new configuration to file + ".new" extension, rename later
- free the configuration tree on exit from load_state()/save_state()
- call snd_config_update_free_global() at the end of command blocks

.... and add configure switch for it.
/etc might be on a read-only partition which is not suitable for dynamic
data such as the mixer settings. Hence move the location of asound.state
to /var/lib.
This is based on a patch from Ubuntu/Debian which hardcoded the pah in
/var/lib.

By doing this we move them from the .data section to .rodata setion,
or from .data.rel to .data.rel.ro.
The .rodata section is mapped directly from the on-disk file, which is
always a save, while .data.rel.ro is mapped directly when using
prelink, which is a save in a lot of cases.

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.

Set -F option as default for restore. There are still too many systems
that are too lazy to set -F option...
Added the new -P option to back to the old behavior.
adds a space in the help text between "restore" and "<card>" and indents
the rest of the text accordingly to fit.
From: Tomas Pospisek <tpo2@sourcepole.ch>
Support store/restore of user-defined controls.
Also, the numid is no longer checked when -F option is given.
The element is determined only from the given name, iface, index, device and
subdevice.
