This adds a flag, -p,--presentation-timings, that enables input lag measuring using the presentation time Wayland protocol. When enabled, we store a timestamp when we *send* a key to the slave. Then, when we commit a frame for rendering to the compositor, we request presentation feedback. We also store a timestamp for when the frame was committed. The 'presented' callback then looks at the input and commit timestamps, and compares it with the presented timestamp. The delay is logged at INFO when the delay was less than one frame interval, at WARN when it was one frame interval, and at ERR when it was two or more frame intervals. We also update statistic counters that we log when foot is shut down.
