In a mode of 'monitor', when given no argument, all of available control
node is observed for their events. At present, discovering the nodes is
done according to sound card number, instead of listing nodes in
configuration space of alsa-lib.
This commit adds a structure to discover sound cards with a simple
interface.

aplay tries to check the file size via fstat() at parsing the format
headers and avoids parsing when the size is shorter than the given
size. This works fine for regular files, but when a special file like
pipe is passed, it fails, eventually leading to the fallback mode
wrongly.
A proper fix is to do this sanity check only for a regular file.

On my 32 bit armhf board arecord exits because of write() returning EFBIG
when the output file size reaches 2147483647 bytes.
To fix this, include generated header file before system header files

This fixes a bug when trying to play files with size
smaller than maximum supported header size.
Lets have a look at the following example:
$ aplay -s 2 sample.raw
-> playback_go(fd = 10, loaded = 26, count = 2, name="sample.raw")
--> l = loaded = 26
--> c = count - written = 2
--> c -= l = 2 - 26 = -24
---> r = safe_read(fd, audiobuf + 26, -24)
---> r = -1, EXIT_FAILURE
In this case we have already 'loaded' from the input file more
bytes that we need to send to pcm device. So, we need to adjust
the number of bytes loaded and avoid reading a negative number
of bytes.

This introduces read_header function which tries
to read the header of an audio file in order to determine
its type.
This has the following effects:
(1) makes code easier to read
(2) don't abort if file size is less than expected header
(2), allows us to play small files with size smaller than any
supported audio file headers.

BIOS vendors typically reuse the same definitions between different
platforms and expose the relevant hardware by changing the value of
the _STA method.
For example on the Asus T100HA, there are 3 HID values for audio
codecs in the DSDT table but two have a zero status and will be
ignored by the ACPI subsystem.
$ more /sys/bus/acpi/devices/10EC*/status
::::::::::::::
/sys/bus/acpi/devices/10EC3270:00/status
::::::::::::::
15
::::::::::::::
/sys/bus/acpi/devices/10EC5640:00/status

/sys/bus/acpi/devices/10EC5648:00/status

This information is very useful to figure out which HIDs/quirks need
to be supported. Add log to alsa-info.sh to only expose non-zero
results of the ACPI _STA method, e.g.

`/lib/systemd/system/alsa-restore.service` specifies
`StandardOutput=syslog`. This overrides the `DefaultStandardOutput`
setting from `/etc/systemd/system.conf`, which the system administrator
can use to specify how output gets logged. In particular, the sysadmin
may want output to go to the journal, or to syslog, or nowhere at all [1].
This patch removes the definition entirely, so the units can use the
system default.
Upstream the patch from the Debian package [2].

The same $xmlto variable is used both in AC_ARG_ENABLE and
AC_CHECK_PROG, but the latter is not setting a value to it when the
program is not found.
These two facts result in the "yes" value from the AC_ARG_ENABLE macro
to be still kept in the variable when the program is not found by
AC_CHECK_PROG, causing USE_XMLTO to be always set, finally resulting in
a build failure in case the xmlto program is not actually in the PATH.
As possible fix could have been to set "no" as a value in AC_CHECK_PROG
when program is not found.
However using two separate variables is more explicit, so fix the issue
this way.

The channel selection currently does not work properly when a channel
map control is provided but no manual channel map was explicitly
requested with "-m".
For example, the CEA/HDMI 6ch (surround 5.1) map is:
FL, FR, LFE, FC, RL, RR.
Tested command: speaker-test -D hdmi -c 6 -t wav
Speaker-test tries to play channels in this following order:
0 - Front Left
3 - Front Center
1 - Front Right
5 - Rear Right
4 - Rear Left
2 - LFE
But wav file played on associated speakers are not aligned. Here are
the real files played:
0- /usr/share/sounds/alsa/Front_Left.wav => OK
3- /usr/share/sounds/alsa/Rear_Right.wav => OK
1- /usr/share/sounds/alsa/Front_Right.wav => OK
5- /usr/share/sounds/alsa/Rear_Center.wav => KO
4- found file /usr/share/sounds/alsa/Front_Center.wav => KO
2- /usr/share/sounds/alsa/Rear_Left.wav => KO
Issue is that associated wav files ordering is reworked only if
channel_map_set variable is set.
Fix consists in allowing wavs re-ordering if a channel mapping as been
get or set, i.e. channel_map is not null.
