This is the second version of the mmio vs. CS flip race fix.
Since v1 I fixed one if Chris's complaints. I still left the
flip_count_after_eq() untouched so that it's reasonably consistent
with the vbl_count_after_eq() I have in my watermark series.
The IPS vs. vblank wait removal patches got reordered.
And I realized we have another race with the primary enable/disable
logic in the sprite code, so I added a fix for that as well.
And finally I tried to kill off some code duplication in the .queue_flip()
functions.
I also wrote a few testcases that exercise these bugs.
