8403967669 alsactl: add locking for per-card initialization
Introduce the -K,--lock-dir parameter to specify the locking
directory. If the locking is active, files card<NUM>.lock
are used to serialize the multiple initialization requests
(udev, service).

Allow the relative -O,--lock-file argument (it's default now).

17b4129e6c alsactl: add 'clean' command to remove the application controls
It is handy to remove all card controls created by applications.

This change allows to remove those controls for all cards, selected
card or selected card with a control id filter list like:

   alsactl clean 0 "name='PCM'" "name='Mic Phantom'"

f1eba0b5de alsactl: Only start restore service when asoundrc file exists
This solves the chicken and egg problem on fresh installations whereby
the alsa state file does not yet exist, and alsa-restore unit attempted
to launch without first having a state file.

f72a296d23 alsactl: Move systemd unit start-up from basic.target to sound.target
Ensures soundcard is ready before restoring state.

sound.target added to systemd in v18:
https://cgit.freedesktop.org/systemd/systemd/commit/?id=88dfa2938af

Simplify dependencies:
 - After=alsa-state.service is not needed because both units test for
   @daemonswitch@ with opposite outcomes.

 - After=sysinit.target is automatically added by systemd.

First proposed by Tom Yan.

7d6673cc13 alsactl: Manage both save and restore in a single unit
With RemainAfterExit=true, we can manage both save and restore of the
card state in a single unit file.  This will fix also the case where
systemd reloads the service; with two individual units, it will
restore the previous state before saving, and may lead to inconsistent
state suddenly.

Also fix alsa-state.service as well to make both start and stop
working in a simpler way.

be4565c841 alsactl: Do not run udev rule before datadir/sbindir are both mounted
Sometimes 90-alsa-restore.rules is run before /usr is mounted,
and alsactl restore depends on /usr/share/alsa being present.

If /usr/share/alsa is not present, we're so early in the boot
process that alsa-restore.service (or upstart equivalent) will
run later on.

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.

a97bcd19dc alsactl: Add a --with-udev-rules-dir configure option.
After the previous patch to install udev rules it is impossible to do a
non-root, custom-prefix make install. This is generally not a problem
when building official packages but it can be a pain for developers
and debuggers etc.

This is essentially the same patch as was already made in PulseAudio
in commit e8a5746f2fcae59bfd18d39b621509b3ef130453.

81f015f5ab alsactl: Move asound.state location to /var/lib/alsa
.... 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.

de7c3eff0e alsactl: systemd and udev hookup
Add minimal systemd and udev support to alsactl so that mixer settings
are restored at boot, when sound cards are plugged in and saved on
shutdown.

This is similar to existing udev/init script solutions in various
distributions.

Note that alsactl is called both synchronously from the udev rules as
well as asynchronously at boot. This is intended, and to ensure two
things:

- At boot the asound.state file might not be readable, since it resides
  on a different file system. That means exclusively restoring sound card
  settings from udev rules will no suffice, since if the rule is
  executed at early boot (for example within udev settle) then the file
  will no be readable and cannot be restored.

- We need to ensure that applications monitoring sound cards coming and
  going (such as PA) must not get these events before the mixer settings
  have been restored. That means the mixer settings must be restored
  synchronously withing the udev rules, before the events are passed on
  to the apps.

That basically means we need to restore the settings once in udev, to
deal with sound cards becoming available during runtime. And once in
early boot to deal with coldplugged soundcards whose data files might
not have been available at time of plugging. Hence we call alsactl
twice: one from the udev rule, and once from he systemd unit file.
