PTHREAD_RECURSIVE_MUTEX_INITIALIZER_NP is not in POSIX, as _NP
(non-portable) suggests.
exposing such a symbol in musl libc would lock in the ABI for all
times and makes it impossible to do future changes to the under-
lying struct without hideous symbol versioning hacks.
use the portable way instead: pthread_once was designed for such
cases.

in POSIX, there is no <sys/signal.h>.
it's merely a legacy alias used by glibc, and the header does nothing
else than including <signal.h>.
so let's do the right thing and use the right name, which works everywhere.

The previous code does not work as expected for some period_size
configurations. We do not rely on the period size value, so do not
correlate the avail_min parameter with this value.

- added -W/--wake option to reduce poll time
- another try to fix the avail_min parameter for playback
- fixed initial silence fill

In some cases it might be usefull to specify another CTL device names.
Add -X/--pctl and -Y/--cctl options.

- added workaround for alsa-lib (pthread configuration parsing issue) -
the workaround must be activated manually using ('--workaround serialopen')
- fixed avail_min initialization (caused high CPU usage or xruns)
- fixed shared buffer initialization (both capture and playback buffers
must have equal number of samples in this config)

alsaloop allows create a PCM loopback between a PCM capture device
and a PCM playback device.
alsaloop supports multiple soundcards, adaptive clock synchronization,
adaptive rate resampling using the samplerate library (if available in
the system). Also, mixer controls can be redirected from one card to
another (for example Master and PCM).
