Finish implementing remaining stuff

[mitchmindtree]

I've noticed that there are bits and pieces around the place that don't seem to be fully implemented - if you get a chance to add all the remaining-stuff-to-do to the issues, I'd be happy to chip away at them when I have the time. It'd be nice to make this the go-to, solid, thorough PA binding :)

Yep some things are not implemented, some thing are platform dependant and i'have only osx and linux to test.
On other big piece which is not implemented is the non-blocking API ( using the port audio callback ), but this was a choice, as i was thinking that it will be as much elegant to write it in Rust in the user program using task the blocking API, than by using the C version.

So i will open some issue, and we can speak, about what could be great or not to add to the binding !
