intel: Use the new DRI2 flush invalidate entrypoint to signal frame done.
Previously for frame throttling we would wait on the first batch after a swap before emitting another swap, because we had no hook after a swap was emitted. This meant that if an app managed to squeeze everything it for a frame had into one batch, it would lock-step with the GPU. With the swapbuffers changes, we now have the entrypoint we want. This takes the WoW intro screen from 25% GPU idle and visibly jerky to 4-5% GPU idle and rather smooth. Other apps such as OpenArena have run into this problem as well.
