- ERESTART not supported platform: use EINTR instead
- add include/os_compat.h, well-used OS specific definition
- copied include/bswap.h from alsa-lib
- EPIPE and ESTRPIPE are different usage, but currently
EPIPE is used when ESTRPIPE is not defined.
To fix this problem, assign ESPIPE instead.

It may be useful to collect the basic sound card information.
The output is in the YAML structured syntax (human and machine readable).

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).

This patch adds --ucm-nodev (or -X) option to get those
messages back. The code works only with library 1.2.6+.
By default, these messages are suppressed:
alsactl[xxx]: alsa-lib parser.c:242:(error_node) UCM is not supported for this HDA model (HDA Intel PCH...)
alsactl[xxx]: alsa-lib main.c:1405:(snd_use_case_mgr_open) error: failed to import hw:0 use case configuration -6

The /var/lib/alsa/card<NUMBER>.conf.d directories should be emptied
when the card is initialized. Implement this functionality directly

Also remove extra snd_config_update_free_global() call for dump-state.
There's a global call in the main() function.

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'"

As man page says: "If successful, the sched_setparam() function shall return zero."
Without update I got this output in the syslog (journalctl):
abr 16 09:25:30 mypc alsactl[1652]: alsactl 1.2.2 daemon started
abr 16 09:25:30 mypc alsactl[1652]: /usr/bin/alsactl: do_nice:165sched_setparam failed: No such file or directory
If sched_setscheduler() returns 0, so it means that the call was successful.

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.

.... 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.
