The recent addition of pause/resume control via keyboard brought
a problem when aplay/arecord is invoked in background. For avoiding
regressions, it's safer to use non-interactive mode as default and
enable the new feature via an option.

When snd_use_case_get_list (and hence also snd_use_case_card_list) returns
an empty list, alsaucm still attempts to free it. This ends up double-
freeing the returned list, or worse, freeing an invalid pointer, depending
on how snd_use_case_get_list gets implemented. Fix alsaucm to return early
on empty lists to avoid this.

snd_use_case_get_list returns lists of strings that are either:
a) A sequence of single strings
b) A sequence of pairs of strings all flattened into a single list
The current list command assumes layout (b) above, and hence prints
nothing when printing a single-entry list that's actually in layout (a).
Add a new command "list1" to dump lists in layout (a).

The CD analog playback line is seldom used these days, as all
modern players rip the CD and use the DAC on the sound card.
In addition, it causes background hum on some machines.
Therefore keep it muted by default.

exp10 is a glibc extension, which isn't supported on uClibc. Luckily,
exp10() is trivial to compute based on exp(), so add a wrapper for
the uClibc case.

Instead of mapping the raw volume values linearly to the screen, use
a mapping where the bar height is proportional to the audible volume,
i.e., where the amplitude is the cube of the bar height.
Signed-off-by: Clemens Ladisch <clemens@ladisch.de>
For controls with a big range, stepping through all values can become
tedious and make it impossible to adjust the volume easily. Therefore,
ensure that all steps are big enough so that the full range has at most
one hundred steps.

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.

/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.

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.

alsaloop allows create a PCM loopback between a PCM capture device
and a PCM playback device.
alsaloop supports multiple soundcards, adaptive clock synchronization,
adaptive rate resampling using the samplerate library (if available in
the system). Also, mixer controls can be redirected from one card to
another (for example Master and PCM).
