Peter Hutterer b48f4c41c0 Add proximity support.
When one of the tools comes into proximity, queue up a proximity event and
send it accordingly.

Includes special handling for tablets that do not send axes with tools
(#29645)

Some tablets send axis values, then EV_SYN, and in the next event the
BTN_TOOL_PEN/BTN_TOUCH, etc. For these tablets, the cursor doesn't move as
coordinates while not in proximity are ignored.

Buffer coordinates received while out-of-proximity and if we get a proximity
event without other coordinates, re-use the last ones received.
