audio: split sample conversion and volume mixing
...
Refactor the volume mixing, so it can be reused for capturing devices.
Additionally, it removes superfluous multiplications with the nominal
volume within the hardware voice code path.

issue snd_pcm_start() when capturing audio
...
snd_pcm_start() starts the capture process and ensures that the events
are delivered to the poll handler. Without the call, capture can be started
only when there is simultaneous playback running.

pcm_ops.run_out now takes number of live samples (which will be always
greater than zero) as a second argument, every driver was calling
audio_pcm_hw_get_live_out anyway with exception of fmod which used
audio_pcm_hw_get_live_out2 for no good reason.

alsa: add host suspend/resume support
...
Both input and output streams may be in SND_PCM_STATE_SUSPENDED
after the host is suspended and resumed, meaning "Hardware is
suspended". snd_pcm_readi() and snd_pcm_writei() will return
-ESTRPIPE if called while the stream is in this state.
Call snd_pcm_resume() to enable audio output and capture after
host resume.

Ignore -Waddress for alsaaudio.c
...
/usr/include/alsa/pcm.h contains:
#define snd_pcm_sw_params_alloca(ptr) do { assert(ptr); *ptr = (snd_pcm_sw_params_t *) alloca(snd_pcm_sw_params_sizeof()); memset(*ptr, 0, snd_pcm_sw_params_sizeof()); } while (0)
The assert generates: "error: the address of 'sw_params' will always
evaluate as 'true'" which combined with -Werror prevents alsaaudio.o
from being built with certain versions of GCC.
