1f656f12cf touchpad: add a struct for handling physical button event state changes
On ClickPads (touchpads without phys. middle/right buttons) it is important to
know whether a physical click is queued up. The finger position or number of
fingers decide which button event to send.

This isn't currently used, we still just send the button number at the moment.

dc13d3ec96 touchpad: move structs into a header file
The tapping state implementation will be in a separate file, so let's make
sure we can access the structs we need.

d22cdf1c47 touchpad: add two-finger average scrolling
If two fingers are down and moving, take the average movement of both fingers
and use that for scrolling.

37a04e0b0d touchpad: add a touchpad driver based on per-finger tracking
This patch is a mixture of an experimental project (libtouchpad) and
evdev-touchpad.c. It adds a new touchpad driver for multi-touch touchpads that
tracks each touchpoint separately. This makes it a lot easier to handle
multi-finger tapping, software button areas, etc.

libtouchpad used a slightly different coding style, this is the attempt to get
closer to the one used in libinput.

Currently sends motion events for single-finger motion, button events only for
physical buttons.

d2e026d8ae Add the shell for a multitouch-compatible touchpad implementation
Doesn't do anything but initialize and destroy. This is not a permanent
separate implementation, it's just easier to start this way and then switch
over than to add to the current one.

Temporary measure: LIBINPUT_NEW_TOUCHPAD_DRIVER environment variable can be
used to enable the new driver
