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.

The term_c_lflag variable might be unitialized in some cases. Add extra
check to avoid setting of wrong value.

Add signal SIGUSR1 to turn over the output file,
--max-file-time to cause the output file to turn over automatically,
and --use-strftime to create output files based on the current time.

Write the process ID to a file so other programs can
signal aplay. When aplay exits, delete the file.

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.

This way the compiler can assume more information about their
interface for optimisation.

In some cases (HDA audio) the ring buffer position values returned
from alsa-lib are inaccurate. The added --test-position option will
print suspicious values.

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.

snd_pcm_drain() doesn't block when running with O_NONBLOCK.
Reset the non-blocking mode before calling snd_pcm_drain() properly
(and restore again for any further operations).
- remove unused static declaration
- fix double close in signal handler
- fix NULL reference
- fix max file size to stdout with non-raw format
- code clean up
