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.

4f29877d54 alsactl: correctly restore dB values of controls with changed range
When the range of a control has changed between driver versions, it is a
good idea to restore the same dB value of the control.  However,
computing the dB value by interpolating betweem the min/max dB values
duplicates alsa-lib's TLV functions and does not even work for controls
with a linear dB range.

A simple conversion to dB and back can be done if we add the dB value(s)
to the saved state.

6232f1c96c Make some static tables and strings constants.
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.
