gestures.h and others: new flags parameter in FingerState.
It can be nice to tag a FingerState object with flags so that one
interpreter may detect a condition and another interpreter may behave
differently.
This CL adds a flags parameter and two flags: WARP_X and WARP_Y. The
warp flags will be used to indicate that a given finger has moved, but
it shouldn't cause motion. This may occur if an interpreter decides
that while we thought the finger was in a given place, we now realize
it's somewhere else.
Also, update the IIR filter to pass flags through, and the Lookahead
filter to track flags in interpolated events.
Finally, for now, we zero the flags parameter in gestures.cc. This
should be removed when xf86-input-cmt is updated to zero this memory.
