a745374232 v4l2: fix port param enumeration for devices without controls 
It is valid for V4L2 devices to not implement any controls. QUERYCTRL
returns ENOTTY in these cases. Enumerating the controls must not fail in
these cases but return no controls.

edd41d8259 v4l2: close v4l2 device on error 
The device needs to be closed when the enum_controls function is exited,
but is not closed if the VIDIOC_QUERYCTRL fails. Fix it.

1c6cb049ce audioconvert: add an option generate silence noise 
Add an empty.noise option that specifies the number of bits to
use for noise when the input signal is pure silence.

Some amplifiers can go into suspend mode pretty easily when they
get pure silence. With empty.noise = 1, audioconvert will now generate
a bitpattern that can keep those amplifiers alive, together with
disabling suspend in the session manager.

Fixes #705

f2dee23085 buffer: add EMPTY chunk flag 
Add an EMPTY chunk flag to mark a piece of memory as 'empty'. For audio
this means silence.
Use the empty flag to avoid mixing 0 samples.
Set the empty flag in output buffers on audioconvert.

6bfe9a362c audioconvert: avoid crash on 64 channels + monitor enabled 
this->monitor enabled adds an additional port in reconfigure_mode. If
there was already the maximum 64, this will crash.

Make maximum number of ports one larger than max channels to avoid
problems.

0f62d3442c alsa: handle driver bugs better 
Use the NEAREST flag when setting a format. This only works for raw
formats and will update the format with the nearest accepted rate
or channels. We can then query the real configured format and use that
for the converter.

This makes things work when a driver tells us it can do 44100Hz but then
refuses and changes the rate to 48000.

See #2197, #2457, #2455, rhbz#2096193

ecc0eecf0f mixer-dsp: mix a quantum of data at a time 
When there is no input, mix up to a quantum of data. Otherwise we might
send too much data to the next node and cause a delay if it does not
handle this.

40f50deae9 alsa: remove NoteOn 0-velocity fixup 
Pass MIDI events as they are.

JACK requires NoteOn 0-velocity midi events to be patched to NoteOff
events for compatibility with LV2 plugins. Let's do this patchup in
the JACK layer then and add an option to disable it.

It's best to pass the midi messages unmodified and then patch them up
wherever they need patching up.

d13a206866 audioconvert: fix resampler in_offset 
Only advance the in_offset with the number of samples that were consumed
by the resampler. In case when the resampler is filling up an old
buffer, this can be less than n_samples.

Fixes a2dp source and possibly others.
