Otherwise, when building with fortify-headers, I get an error because
the compiler doesn't know pwtest_ptr_notnull will not return if the
passed pointer is null, so it doesn't know the pointer subsequently
passed to memmove via pw_array_remove will be non-null.

Heavily inspired by libinput's litest framework (built around check), this is
a from-scratch framework that simplifies adding tests for various parts of
pipewire. See the pwtest.h documentation for details but the basics are:
- PW_TEST() and PWTEST_SUITE() specify the tests to be run
- Test are run in forked processes, any errors/signals are caught and printed
to the log
- Tests have a custom pipewire daemon started on demand to talk to [1]. The
daemon's log is available in the test output.
- Output is YAML to be processed into whatever format needed
[1] There are limits here, since we can't emulate devices yet there is only
so much we can rely on with the daemon.
