So that the pipewire thread is running with RT priority.

5ee9133b60 alsa plugin: allow specifying a media.role on the virtual device name 
So that we can do:
  aplay -D pipewire:ROLE=Music music.wav
  aplay -D pipewire:ROLE=Notification notice.wav

0054319d88 meson.build: add -D_GNU_SOURCE to the project arguments 
This appends it to every compilation command so we can get rid of the c_args
for (almost all) executables.

e0471c6757 pipewire: allow NULL pointers in pw_properties_free() 
Just like the real free() we should just ignore a NULL pointer, makes the
caller code easier for those instances where properties are optional.

Patch generated with concinelle with a few manual fixes.

5a186ece01 alsa: handle plugin errors better 
When the plugins can't be loaded, we fail to make a main_loop.
Handle this case instead of segfaulting.

See #1239

separately.

2405f0942b spa/buffer: rename SPA_MEMBER to SPA_PTROFF 
SPA_MEMBER is misleading, all we're doing here is pointer+offset and a
type-casting the result. Rename to SPA_PTROFF which is more expressive (and
has the same number of characters so we don't need to re-indent).

29be757598 pipewire-alsa: fix drain for capture 
Since pw_stream doesn't call the drained callback after flush for
capture it has to be called explicitly from process.

0aadc0450d alsa: implement poll_descriptors 
In there we can evaluate the poll fd and make sure it blocks or not
in the following poll based on the buffer filled levels. Some API
is very sensitive about this, it seems.

Fixes #433

8386ddff78 alsa-plugin: Fix default channel layout 
We need to use the default channel layout that alsa clients expect.
Remove query chmap, nobody uses that, we need to use the alsa default
channel map.
Implement set_chmap in case anybody wants to set a custom map.

fd520c4b39 alsa-plugin: set buffer size correctly 
Our output buffer size is always what is needed to produce one
period of samples. We use nframes from the hardware and the rest
we fill with silence.

Keep track of how many samples we need to produce. If we don't have
enough samples in the ringbuffer, fill the rest with silence.

92c541ea03 pipewire-alsa: Make sure to always fill the pipewire buffers with 
silence on process if there is not enough data.
This fixes noise with the retroarch alsa backend on pause, which doesn't
actually pause the device.

743cf58fb7 Define SPA_FALLTHROUGH to make fall-through annotations work for all compilers 
This is needed for example for Clang compiler which uses different
annotations than GCC. It will make WebRTC to happily use PipeWire
since the spa library is header-only and WebRTC defaults to use
Clang with -Wimplicit-fallthrough.
