Documentation doesn't mention threading rules consistently

[PieterPenninckx]

The LV2 documentation mentions threading rules. It appears that lilv doesn't attempt to apply thread synchronisation (it doesn't "abstract away" the threading rules as far as I can see). The documentation mentions some threading classes, but not everywhere. In particular, it's not clear from the documentation whether lilv_instance_run and lilv_instance_deactivate can be called concurrently.

Fair enough, although these functions are just trivial (as "trivial" as can be, see the header) wrappers for the corresponding LV2 functions. It was probably a mistake to add them at all, but at the time I thought it was more friendly to have a whole API that's consistently like lilv_do_whatever() that can be used to run a plugin.

Fixed in ecd0743, thanks.
