Adding Mesa Quirk 'NoSetSwapIntervalPostRetarget': SIGSEGV on setSwapInterval() after changing the context's drawable w/ 'Mesa 8.0.4' dri2SetSwapInterval/DRI2 (soft & intel)

Analyzing 'TestGLContextDrawableSwitchNEWT' crash at setSwapInterval -> dri2SetSwapInterval
after retargeting the context (new drawable association).
Turns out Mesa's dri2SetSwapInterval may have a bug.
