Set BTN_TOUCH, BTN_TOOL_DOUBLETAP automatically depending on the number of
fingers down.
This emulates real event sequences a bit better than the current approach,
though it's not a 100% correct emulation:
1) On real devices, BTN_* are usually sent last before the SYN_REPORT - here
they are sent first to slot in with the custom, device-specific event
sequence. We should only ever look at the complete sequence anyway, so this
shouldn't matter.
2) On real devices, the switch from BTN_TOOL_DOUBLETAP to TRIPLETAP and vice
versa is not always toggled within the same SYN_REPORT
3) On synaptics devices, BTN_TOUCH is released in the frame where
BTN_TOOL_DOUBLETAP is set. It is then immediately set again in the next
frame. With the current litest framework this is hard to integrate, so we
just leave BTN_TOUCH set the whole time, which is what MT devices do if
they don't have BTN_TOOL_DOUBLETAP.

On small touchpads, a touch that intends to go across the width of the
touchpad is likely to start in the edge zone. Likewise, on those touchpads the
chances of a palm event happening on the edge is small.
A minimum width of 8cm determined by an elaborate process of completely
unscientific guesswork: the x220 is roughly 7.5cm across and doesn't suffer
much from edge events, the T440s is 10cm across and definitely suffers from
it. So the trigger width likely somewhere in between which makes 8cm about as
valid as any other guess.
Note that this disables palm detection for resolution-less touchpads too - if
we don't know how big the touchpad is we can't know if palm detection on the
edges is necessary.

Using a 0-100% range is useful but in some cases we need events with finer
than 1% granularity.
And fix up the two-finger test that now fails. This was a bug in the test
anyway, the dx/dy supplied here was 1% of the touchpad width. Confined to
integers this meant we only ever had the touch down, then the single move by
1%. That caused two events - not enough to satisfy tp_estimate_delta, so we
always had a delta of 0/0 regardless of the size of the move.
Now with doubles this fails, so drop it to 0.1% instead, which is small enough
on all touchpads we currently have.

We send two delta events. One may get eaten or softened by the accel code but
our expectation should be that both may get through, so the length of the
expected vector is √((2dx)² + (2dy)²). That is the maximum length we expect
though for deltas ranged [-1, 1].
Deltas above the threshold would fail this test but we can fix that when
needed.
Pointer acceleration is subject to timing changes. When running tests in
valgrind pointer accel timeouts and tracker resets may happen so we can't
guarantee a specific acceleration length.

Two basic tests are added to check for the tap default setting - which is now
"tap disabled by default", for two reasons:
* if you don't know that tapping is a thing (or enabled by default), you get
spurious button events that make the desktop feel buggy.
* if you do know what tapping is and you want it, you usually know where to
enable it, or at least you can search for it.

The current code triggers multi-finger tapping even if the finger released was
previously held on the touchpad for a while. For an event sequence of:
1. first finger down
2. first finger move past threshold/wait past timeout
3. second finger down
4. first finger up
The second finger initiates the two-finger tap state, but the button event is
sent when the first finger releases - despite that finger not meeting the
usual tap constraints. This sequence can happen whenever a user swaps fingers.
Add the finger state to the actual touchpoints and update them whenever the
constrains are broken. Then, discard button events if the respective touch
did not meet the conditions.

If the user puts down to fingers to scroll, then changes his mind and
lifts them, without having them moved past the initial scroll threshold in
either direction, then any movement which he has done will cause a spurious
scroll event when the second finger down is lifted first.
The problem is that t->is_pointer was not being set to false in this case,
since that is done in tp_post_twofinger_scroll after checking scroll.state
which never gets set in this scenario.
Instead of changing the order, simply completely remove scroll.state completely
it is a boolean, and everywhere we check for it we also check for the axis bits
in state.direction, so it is not necessary.
Also add a check to ensure there are no spurious motion events.
