For devices that are incapable of reporting per-contact distance and can
only report ABS_DISTANCE, just distance is not enough for upper layers of
OS to determine whether contact is leaving the area or if it is continuing
hovering, we need BTN_TOOL_FINGER for that:

                                   Contact State
                    Inactive          Hovering            Active
                   (far away)    (inside hover area)  (touching surface)
BTN_TOUCH              0                 0                   1
BTN_TOOL_FINGER        0                 1                   1
ABS_DISTANCE          N/A                1                   0

<id>urn:sha1:c627589282213bbef12a482c0b87f23526ceb3f0</id>
<content type='text'>
The case occurred recently with a touchscreen using twice a slot during a
single EV_SYN event:

E: 0.288415 0000 0000 0000      # ------------ SYN_REPORT (0) ----------
E: 0.296207 0003 002f 0000      # EV_ABS / ABS_MT_SLOT          0
E: 0.296207 0003 0039 -001      # EV_ABS / ABS_MT_TRACKING_ID   -1
E: 0.296207 0003 002f 0001      # EV_ABS / ABS_MT_SLOT          1
E: 0.296207 0003 0035 0908      # EV_ABS / ABS_MT_POSITION_X    908
E: 0.296207 0003 0036 1062      # EV_ABS / ABS_MT_POSITION_Y    1062
E: 0.296207 0003 002f 0000      # EV_ABS / ABS_MT_SLOT          0
E: 0.296207 0003 0039 8787      # EV_ABS / ABS_MT_TRACKING_ID   8787
E: 0.296207 0003 0035 1566      # EV_ABS / ABS_MT_POSITION_X    1566
E: 0.296207 0003 0036 0861      # EV_ABS / ABS_MT_POSITION_Y    861
E: 0.296207 0003 0000 0908      # EV_ABS / ABS_X                908
E: 0.296207 0003 0001 1062      # EV_ABS / ABS_Y                1062
E: 0.296207 0000 0000 0000      # ------------ SYN_REPORT (0) ----------

This occurred because while having already slots 0 and 1 assigned, the
touchscreen sent:

0.293377 Tip Switch: 0 | Contact Id: 0 | X:  539 | Y: 1960 | Contact Count: 3
0.294783 Tip Switch: 1 | Contact Id: 1 | X:  908 | Y: 1062 | Contact Count: 0
0.296187 Tip Switch: 1 | Contact Id: 2 | X: 1566 | Y:  861 | Contact Count: 0

Slot 0 is released correclty, but when we look for Contact ID 2, the slot
0 is then picked up again because it is marked as inactive (trackingID &lt; 0).

This is wrong, and we should not reuse a slot in the same frame.
The test should also check for input_mt_is_used().

In addition, we need to initialize mt-&gt;frame to an other value than 0.
With mt-&gt;frame being 0, all slots are tags as currently used, and so
input_mt_get_slot_by_key() would return -1 for all requests.

The recent inclusion of a deassignment cost in the slot assignment
algorithm did not properly account for the corner cases where the
solutions are overcovered. This change makes sure the resulting
assignment is unique, allocating new slots when necessary.

Some devices are not fast enough to differentiate between a fast-moving
contact and a new contact. This problem cannot be fully resolved because
information is truly missing, but it is possible to safe-guard against
obvious mistakes by restricting movement with a maximum displacement.

The new problem formulation for dmax &gt; 0 cannot benefit from the speedup
for positive definite matrices, but since the convergence is faster, the
result is about the same. For a handful of contacts, the latency difference
is truly negligible.

Commit f8ec894945e7d205ce62be59e55e72c4304e4739 allowed external callers
use slot dropping logic, unfortunately it also broke external users of
input_mt_is_used() as we stopped incrementing frame count unless input
device was set up to automatically drop unused slots.

Fixes: f8ec894945e7d ("Input: MT - make slot cleanup callable outside
mt_sync_frame()")

Some semi-mt drivers use the slots in a manual way, but may still
want to call parts of the frame synchronization logic. This patch
makes input_mt_drop_unused callable from those drivers.
