There is no support for resuming streamout. Furthermore, this also
controls glDrawTransformFeedback functionality which requires the same
ability to query how many primitives were sent out of TF.

I have a partially-working patch for bringing this back, but it's not 100%
quite yet - some sort of issues with concurrency I have yet to track down.
However in the current state, this is just totally not supported by the FE
(but the swr core does do this).
