vulkan_headers was a workaround for distributions providing pkg-config information
without the headers. Replacing it with a more conventional have_vulkan
and assert header availability if the option vulkan is enabled.
At the moment, cross compilation may not work in certain cases because
checks are carried out against the build machine instead of the host machine.
Replace uses of `build_machine` with `host_machine` to fix that.
In native compilation, all three "machine objects" available in meson
are the same, so this change should have no effect in that case.

Move all backends to dynamic libaries loaded with spa_plugin_loader so
new backends not needs changes in pipewire or pipewire dependency to
external code

Since meson 0.59.0, a feature object has an `allowed()`
method which returns true when the feature is set to
'enabled' or 'auto'.
Utilize that instead of the previously used
not feature.disabled()
Until now the 'v4l2' feature was not actually checking that its
required header has been found, this commit adds a check for
<linux/videodev2.h> and correctly reports both header status and whether
the feature itself ends up enabled (depends on libudev).
`av_register_all()` is the only thing used from libavformat,
but that doesn't seem to be needed for codec enumeration,
so remove it, and call `avcodec_register_all()` instead
when libavcodec < 58.10.100.
Makes a device with a source and sink that automatically
proxies all physical ports from jack. Jack then drives our
PipeWire pipeline from its own thread.
If these optional plugins are enabled in meson options,
then the dependencies should be required to proceed.
It is not cool to compile with let's say bluez5 explicitly
enabled and after compilation discover that bluez was not
found and meson silently skipped that plugin.
Replace the AsyncDone event with an explicit done callback in the node
to signal completion of an async operation.
Pass read and write fd together with the transport
Move the proxy plugin to the client-node
Move serialization code to pinos because its specific to pinos
Move some functions to the .h files
Make the mapper dynamic
We now only allow per port preallocated buffers. We exchange the index
into the array instead of passing the buffers around. We still use the
refcount to track when a buffer can be reused.
Improve API a little, allow passing the node as the first argument of
the interface call.
Implement alloc_buffer in v4l2 and improve the test.
