Emil Velikov 58459a57fa tests/nouveau: automake: fold C and CPP flags
Since we don't have any C++ souces this should be a no-op. Folding the
two seems to be the common practise throughout the repo.

Maarten Lankhorst 5ea6f1c326 nouveau: make nouveau importing global buffers completely thread-safe, with tests
While I've closed off most races in a previous patch, a small race still existed
where importing then unreffing cound cause an invalid bo. Add a test for this case.

Racing sequence fixed:

- thread 1 releases bo, refcount drops to zero, blocks on acquiring nvdev->lock.
- thread 2 increases refcount to 1.
- thread 2 decreases refcount to zero, blocks on acquiring nvdev->lock.

At this point the 2 threads will clean up the same bo.
