A few patches from my audio patch queue.
Patches 1 - 2:
If a guest selects an unsupported sample rate, an error message is
currently shown. The first patch takes care to suppress the error
message and reports with the qemu_log_mask(LOG_UNIMP, ...) function
that this is not supported. The second patch is needed because there
are two code paths to reach the qemu_log_mask() function in the
audio_pcm_sw_alloc_resources_* functions. The second path prints an
additional error message up to now.

Patches 3 - 4:
General improvements.
Patches 5 - 9:
These patches remove the audio_calloc() function. The GLib g_new0
macro is a better replacement for audio_calloc(). There's one
exception where g_malloc0() fits better.
Patches 10 - 11:
Audio playback and recording with the ALSA audio backend currently
doesn't work well with the default audio settings.
v2: Address Daniel's comments
[PATCH v2 07/11] audio/audio_template: use g_malloc0() to replace
audio_calloc()
The n_bytes argument of g_malloc0() is now always > 0 at this call site.
[PATCH v2 08/11] audio/audio_template: use g_new0() to replace
audio_calloc()
Check samples for negative values. It's possible to have negative
samples due to overflows or unsigned to signed conversions. Patch
01/11 takes care of samples == 0.
Volker Rümelin (11):
audio: log unimplemented audio device sample rates
audio: don't show unnecessary error messages
audio: rename hardware store to backend
