alsactl: Read only *.conf files when a directory is passed via INCLUDE
When alsactl init is invoked and a directory path is passed to INCLUDE
command in the config file, read only *.conf files in that directory.
This will avoid reading backup files or invalid files that have been
created accidentally.
Also by using scandir() with alphasort(), alsactl reads the files in
alphabetical order. Thus it's highly recommended to use some number
prefix to the file name for assuring the order.

alsamixer: Fix X-win related crash for PulseAudio plugin (bad linking)
A lot of reports that alsamixer crashes in X terminal when the PulseAudio
CTL plugin is activated were entered to the tracking systems.
I figured that there is a linking clash for the shutdown() function.
The shutdown() function in glibc is socket related, but the alsamixer code
redefines this function and appearently that under some linking
circumstances - which PA client invokes during the runtime dynamic linking
- the wrong function is called.
This patch, for safety, renames the shutdown() function from alsamixer
to app_shutdown(), but it might make sense to figure the real linking
culprit to avoid future surprises.

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.
