[Bf-cycles] osl node

[Lukas Tönne]

Great :)

Maybe with the compile function being part of render engine API we can
get rid of the global shader update tag easier now (marked as a XXX
hack).

The refresh time is also quite annoying still. The lagging UI was what
i tried to fix with the patch for device cancelling, which turned out
to be too unstable ([1], [2]). If individual shader updates can reduce
this UI lag sufficiently that would also be ok.
