fallback: hires scroll heuristics for buggy devices
Some devices might announce support for high-resolution scroll wheel
by enabling REL_WHEEL_HI_RES and/or REL_HWHEEL_HI_RES but never send
a high-resolution scroll event.
When the first low-resolution scroll event is received without any
previous high-resolution event, print a kernel bug warning and start
emulating high-resolution scroll events.
Fix #668
