This is needed specifically for Qualcomm devices using DRM fbdev
emulation, it is probably useful for other platforms using fbdev
emulation.
Libinput doesn't buffer events, so hook up a dedicated thread per input
device and a small circular queue to buffer input events. This fixes the
dropped input issue so you can type much faster. If there are too many
events, the oldest events in the queue will be dropped.
