This makes it easier to test PipeWire in its "as-installed" state,
for example in an OS distribution.
The .test metadata files in ${datadir}/installed-tests/${package} are
a convention taken from GNOME's installed-tests initiative, allowing a
generic test-runner like gnome-desktop-testing to discover and run tests
in an automatic way.
The installation path ${libexecdir}/installed-tests/${package} is also
a convention borrowed from GNOME's installed-tests initiative.
In addition to the automated tests, I've installed example executables
in the same place, for manual testing. They could be separated into
a different directory if desired, but they seem like they have more
similarities with the automated tests than differences: both are there
to test that PipeWire works correctly, and neither should be relied on
for production use. Some examples are installed in deeper subdirectories
to avoid name clashes.

We only need as many ports and buffer data as the maximum number
of channels, which is 64.
Fix empty output size. We're only ever going to fill this with
float samples.
Channelmix has now a control port that receives control sequences. Each Control
of those sequences are handled individually by channelmix in order to change
properties when a specific amount of samples have been processed.

Make a new DRAINED status.
Place the DRAINED status on an input IO when a stream is out of
buffers and draining.
All nodes that don't have HAVE_DATA on the input io need to copy
it to the output io and return the status. This makes sure the
DRAINED is forwarded and nodes return DRAINED from _process()
DRAINED on the resampler flushes out the last queued samples and then
forwards the DRAINED in the next iteration.
Emit a new drained signal from the context when a node returns
DRAINED. Use this to trigger the drained signal in the stream.
Abuse the xrun callback in the adapter to emit the drained signal until
almost all data left the resampler. This needs more work with a proper
signal and a buffer flag to signal the drain.
We should not have to initialize the state to NEED_DATA, anything
that is not HAVE_DATA is good. Also we need to set the buffer to
INVALID because else it might be recycled.
