The `LoopUtils` interface can be used on platforms that don't
support the Linux-specific `timerfd` interface.
Added `local-videotestsrc` to validate the plugin still functions.
Restructured the SDL event loop as the window would not update
under WSL2, resulting in a black window being shown. All rendering
in SDL2 must happen on the same thread that originally created the
renderer.
To prevent the SDL event loop from being starved, we make sure to
poll it at least every 100 ms.
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.

Example executable that runs an output audioadapter using audiotestsrc as slave
with an input audioadapter using alsa-pcm-sink as slave for easy testing.
FreeBSD doesn't provide timerfd and eventfd functions. These are implemented in
3rd party library called epoll-shim. Link targets requiring these functions to
this library.
