pulseaudio: remove rtkit dependency and update to 14.2

[ericonr]

PulseAudio doesn't need rtkit available to work for basic usage, so
it's better to only pull it in when a user wants realtime (the error
messages should also be clear enough).

Since rtkit now pulls in a complex dependency in polkit, we can avoid
pulseaudio also pulling the whole thing in.

I have yet to test this throroughly. Basic functionality is fine.

no, not really

this will just result in 1) people not knowing what to install when they need it 2) rtkit becoming an orphan and getting autoremoved on existing systems

you just shouldn't have added polkit dependency in rtkit in the first place

Why not, https://github.com/heftig/rtkit/blob/master/README#L226 says it is needed (is upstream just wrong about requirements for their own software (wouldn't be the first time lol))

hm, but https://github.com/heftig/rtkit/blob/c295fa849f52b487be6433e69e08b46251950399/meson.build#L21 says that it is optional.

[ericonr]

@fosslinux it's optional only because they can use it to determine where to dump the polkit config file https://github.com/heftig/rtkit/blob/c295fa849f52b487be6433e69e08b46251950399/meson.build#L53 , otherwise they have a fallback. And this is at build time, not at runtime (you shouldn't check for runtime dependencies like that at build time, after all).

[fosslinux]

Oh, duh, silly me! Yeah, ofc it wont detect for runtime at buildtime lol
