Paprefs should use server version when checking for modules

[willdyson]

When paprefs checks for availability of modules, it does so using a compiled-in path to the directory where they live. However, the module path contains the version number of libpulse.

This means paprefs must be recompiled whenever libpulse is upgraded, even though it does not link against libpulse at all!

It would be much better if paprefs would obtain the current server/library version and use that to construct the path to the modules files.

Ideally, libpulse would export a function to check if a given module is available for loading...

Actually I'm ultimately going to be moving paprefs into pavucontol in some capacity and deprecating module-gconf in favour of a built in module-loader, so this problem will go away when I get around to finishing that off... (still got a bit to do on it).

There's a debian patch against 0.9.9 which implements this in paprefs, if you'd like to fix this now before merging paprefs into pavucontrol.

Yeah, may as well. We can probably push out a final paprefs release at some point as I've not really made all that much progress on the loader stuff of late (tho' will catch up on it sometime soon hopefully!)

Pushed to master.

Thanks again :)
