We need to remember whether a tap was down or just hovering, otherwise we mess
up the state machine when we send tap release events for taps that never
switched to TOUCH_BEGIN. This is quick fix, really we should have a new state
here, but that's a lot harder to implement.

As we switch to pressure-based touch detection, we need for all
pressure-capable touchpads to send pressure values. They'll do so by filling
in an axis default but that breaks our current hover code.

Make sure the hover litest helpers force a pressure of 0.

Now that the acceleration code doesn't use dpi-normalized coordinates anymore,
we don't need to use them in the touchpad code. Switch to physical distances
instead, it makes debugging a lot saner.

Make sure the events we deal with are the ones we actually honor. This reduces
the chance that we accidentally process events we weren't event supposed to
get based on some earlier device decision.

./configure --enable-gcov adds the required flags to link everything ready for
gcov. A new make gcov target runs the test suite, then pulls all the gcov bits
together into ./test/gcov-reports/ including a summary file.

The script to pull everything out is used in libevdev too, we just have an
extra condition here to ignore the selftest gcov bits (it overwrites the
useful litest.c coverage output).

When the filter code switched to raw device coordinates (bdd4264d) the input
data remained in device coordinates. Since the factor for touchpads was still
based on the physical velocity (and thus all touchpads get the same
acceleration factor for identical moves), the actual delta was dependent on
the resolution. e.g.

touchpad with 40u/mm: delta of 2/2 * accel factor 2 -> accel delta of 4/4
touchpad with 20u/mm: delta of 1/1 * accel factor 2 -> accel delta of 2/2

The normalized coordinates should be independent of the touchpad's resolution
though.

Affected by this was the standard mouse accel code and the touchpad accel
code, other filters always returned unnormalized coordinates (separate bug,
not addressed here).

This patch restores the correct behaviour for mice and touchpads
while leaving the special filters untouched. For comparision:
* 1000+dpi mice: accelerate normalized, return normalized
* touchpads: accelerate unnormalized, return normalized
* low-dpi mice: accelerate unnormalized, return unnormalized
* trackpoints: accelerate unnormalized, return unnormalized
* x230: don't touch, already does the right thing
