The current mtdev is not ABI stable, and the upcoming additions
to the kernel api will break ABI. This patch starts the process
of keeping binary compatibility with old programs, by moving the
abi-specific parts under a special flag, MTDEV_NO_LEGACY_API,
and makes sure the internal parts compiles with MTDEV_NO_LEGACY_API
set. This way, older programs will still work, old programs will
still compile, and new programs will be able to use the additions.

In case mtdev is driving a non-MT device, basic dimensions are not set
properly. Fall back on ABS_X/Y and ABS_PRESSURE, such that basic
pointer operations can be supported through mtdev.

The current MT slot protocol allows any tracking id outside the range
specified by the device to denote an unused slot. This is difficult to
handle in userspace, since the valid range is unknown. This patch
tightens the definition of a valid tracking id to always lie in the
range [0, MT_ID_MAX], and uses the value -1 to denote an unused slot.
