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.
