dev: Add support for single-pass scan out in the PixelPump
Add a helper function to scan out an entire frame in one time
step. This requires the public PixelPump to be changed somewhat to
separate timing updates from general PixelPump control. Instead of
calling PixelPump::start(timings), timings now need to be updated
using a separate call to PixelPump::updateTimings(timings) before
calling PixelPump::start().
Display controllers that don't need accurate timing (e.g., in KVM
mode), can use the new PixelPump::renderFrame() API to render an
entire frame in one step. This call results in the same callbacks
(e.g., calls to nextPixel()) as the timing calls, but they all happen
in immediately. Unlike the timing counterpart, renderFrame() doesn't
support buffer underruns and will panic if nextPixle() indicates an
underrun.
