Commit 6bbeb78d forgot to change some of VU-meter output to stderr.
This patch makes the output of `aplay -vvv` consistent again.

Because of the way the pcm_read() functions are currently used, returning
rcount or result is equivalent but I feel it is more accurate to
return 'result'.

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.

When aplay/arecord are called without any argument the application hangs forever.
Instead of hanging, print the usage and exit.

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
that open() will support large files if supported, and if not, this
allows us to fall back gracefully to non-LFS open().

aplay is limited to 32 channels, which makes it impossible to use it for
testing devices with more channels. here we increase the limit to 256,
which should be sufficient for a virtual device made of 4 64-channel
soundcards.

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.

I have just discovered a minor logic inversion bug in
aplay/arecord --list-pcms functionality.
Basically, executing "aplay --list-pcms" lists all devices capable of
capture and executing "arecord --list-pcms" lists all devices capable
of playback.

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.

Added the support of stereo VU-meter.
Enabled via -Vs option.
The new option, -V, can be used to enable the VU-meter. Now
VU-meter can be enabled even without -vv.
WAV files with more than 2 channels or with more than 16 bits per samples
can be saved with "extensible format" chunk
(see http://msdn2.microsoft.com/en-us/library/ms713496(VS.85).aspx).
For instance, sox, when converting data to 24- or 32-bits per sample format
uses this format, and aplay was unable to play such file. Now the problem
is solved :-)

This patch modifies aplay/arecord to support playing/capturing IEEE float
32-bit WAV files. Tested on HDA hardware in both stereo and multi-channel
modes. Added the WAV file constant for Dolby AC-3 S/PDIF passthrough to
formats.h for future use when AC-3 passthrough is better supported.
