Hans de Goede 8b23811535 Input: alps - v7: ignore new packets
NEW packets are send to indicate a discontinuity in the finger coordinate
reporting. Specifically a finger may have moved from slot 0 to 1 or vice
versa.  INPUT_MT_TRACK takes care of this for us.

NEW packets have 3 problems:
1) They do not contain middle / right button info (on non clickpads)
   this can be worked around by preserving the old button state
2) They do not contain an accurate fingercount, and they are
   typically send when the number of fingers changes. We cannot use
   the old finger count as that may mismatch with the amount of
   touch coordinates we've available in the NEW packet
3) Their x data for the second touch is inaccurate leading to
   a possible jump of the x coordinate by 16 units when the first
   non NEW packet comes in

Since problems 2 & 3 cannot be worked around, just ignore them.
