The current implementation assumes these are mutually exclusive, but
Yamaha MusicCast requires an auth-setup step following the digest
authentication.
`rtsp_auth_reply` could be dropped in favour of `rtsp_options_reply`,
but you may end up in a loop if the other end keeps responding with 401.
Yamaha MusicCast (or at least the RX-A880) seems to be stricter about
the URI here, as it rejects `*`. Examples, such as those documented by
OpenAirplay, use the real URI.
Clang 15 at least with my build configuration emits warnings about
function prototypes that lack argument types. Most notably this
happens with functions that take no arguments which in compiler view
equates to the void type i.e. void f(void) instead of void f(). As I
understand, this will become an error in some future Clang release,
so might as well fix it now.
Since these were discovered not by a linter but by the actual compiler
for my particular build configuration, some f() may have escaped for
now. But at least it's enough to build PipeWire with most optional
features enabled even when -Werror=strict-prototypes is enabled.
For anyone else wanting to have a go at this, these can be upgraded
from warnings to errors by adding -Werror=strict-prototypes to the
custom CFLAGS which probably works with GCC, too, but has only been
done with Clang 15.0.2.
Finally my editor automatically stripped trailing spaces upon saving
the modified files. I assume it's probably not worth keeping those
invisible bytes around but this may have slightly dubious implications
as it did also turn indented empty lines of JACK license header into
regular empty lines.

In a scenario where pw-link is called without a session manager running,
the output port on a node will not exist. In such a case, we broke out
of the for loop with all_links_exist set to true and returning EEXIST.
The return of EEXIST gives a confusing error message. Fix this.
uint32_t i;
for (i = 0; i < SPA_N_ELEMENTS(some_array); i++)
.. stuff with some_array[i].foo ...
becomes:
SPA_FOR_EACH_ELEMENT_VAR(some_array, p)
.. stuff with p->foo ..
