tools: add libinput analyze buttons for button state analysis
...
This tool helps with tracking button states and time deltas
between button events. Example output for a mouse with LMR buttons
recorded (the mouse also has BTN_SIDE and BTN_EXTRA):
Timestamp │ Delta │ L │ R │ M │ S │ E
0.596112 │ 0ms │ ┬ │ │ │ │
0.689096 │ 92ms │ ┴ │ │ │ │
1.129056 │ 439ms │ ┬ │ │ │ │
1.308178 │ 179ms │ ┴ │ │ │ │
1.469149 │ 0ms │ ┬ │ │ │ │
1.598096 │ 128ms │ ┴ │ │ │ │
1.862125 │ 264ms │ ┬ │ │ │ │
2.084234 │ 222ms │ │ │ ┬ │ │ │
2.415224 │ 330ms │ │ │ ┴ │ │ │
2.831227 │ 416ms │ │ │ ┬ │ │ │
3.215067 │ 383ms │ ┴ │ │ │ │ │
3.525230 │ 310ms │ ┬ │ │ │ │ │
3.629006 │ 103ms │ ┴ │ │ │ │ │
3.813078 │ 184ms │ ┬ │ │ │ │ │
3.909170 │ 96ms │ ┴ │ │ │ │ │
4.093180 │ 184ms │ ┬ │ │ │ │ │
4.317036 │ 223ms │ ┴ │ │ │ │ │
4.507175 │ 190ms │ ┬ │ │ │ │ │
4.587105 │ 79ms │ │ │ ┴ │ │ │
4.779211 │ 192ms │ ┴ │ │ │ │
5.075239 │ 296ms │ │ │ ┬ │ │
5.259097 │ 183ms │ │ │ ┴ │ │
5.379082 │ 119ms │ │ │ ┬ │ │
5.483044 │ 103ms │ │ │ ┴ │ │
The default behavior is to highlight time deltas below 25ms
in red. 25ms is our higher debounce timeout.
Note that the delta time is the one between button events, ignoring any
e.g. motion events in between.

tools: add a tool to print a libinput recording as a table
...
This makes it easier to visualize changes in various axes or key states that
should not be there, doubly so for long recordings.

tools: add a tool to analyze the finger count from a recording
...
Given a libinput recording, print the timestamps of any finger changes, i.e.
which slots are currently logically down. For example:
Timestamp | Rel time | Slots |
--------------------------------------
0.000000 | +0.000s | + | | | |
0.454631 | +0.454s | | | | |
5.065401 | +4.610s | + | | | |
6.140281 | +1.074s | + | + | | |
7.410377 | +1.270s | | + | | |
7.420200 | +0.009s | | | | |
11.233108 | +3.812s | + | + | | |
11.850206 | +0.617s | | | | |
13.827740 | +1.977s | + | | | |
14.704027 | +0.876s | + | + | | |
16.050577 | +1.346s | + | | | |
16.905186 | +0.854s | | | | |
This data is available with the per-slot-delta tool but the output here is
more compressed, making it easier to detect stuck fingers. Pressure
thresholds are not currently supported.

tools: add a libinput analyze command with the per-slot-delta subcommand
...
I've been using this script ever since libinput record was available, might as
well ship it with libinput so I don't have to remember where it lives.
