It is required (exclude the fatal SIGABRT) to call snd_pcm_close() and
the end of work (outside of the interrupt handler). Use new snd_pcm_abort()
function to inform alsa-lib to not ignore EINTR and move the in_aborting
variable to the global scope to be checked in the i/o loops.

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.

Automake-1.13 removed long obsolete AM_CONFIG_HEADER completely (

and errors out upon seeing it.
Attached patch replaces it with proper AC_CONFIG_HEADERS.

When doing control changes by a relative amount, amixer used the wrong
rounding direction, which would make it possible to stay at the same raw
value if the step was not big enough to reach the next value.

When we get a notification that an element has been removed, we have to
recreate our internal control representation to avoid accessing freed
memory. (And the checking for SND_CTL_EVENT_MASK_REMOVE should actually
be done correctly while we're at it.)

Now aplay tries to follow the given channel map by rearranging the
channels even when the channel map override isn't allowed but if the
device is still capable to return a channel map.
Also update the man page appropriately.

With -m option, user can specify the order of channel map.
As of this commit, it just tries to override the channel map, thus it
works only on devices that support the channel map override like HDMI.
Adjusting the channel order in aplay itself will be added later.

AC_SYS_LARGEFILE in configure.in will automatically set up defines so

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.

When -M option is given, amixer handles the volumes in percent unit
with the mapping more intuitive to human ears just like in alsamixer.
The -R option is to take the raw value as the volume percentage.
