[ANNOUNCE] libinput 1.16.0

[Peter Hutterer]

libinput 1.16.0 is now available.

No significant changes since the second RC, so here's slightly polished RC1
announcement text.

This has been a long cycle, mostly because there weren't any huge changes on
the main development branch and a lot of the minor annoyances have found
their way into the 1.15.x releases anyway.

libinput now monitors timestamps of the events vs the current time when
libinput_dispatch() is called by the compositor. Where the difference
*may* result in issues, a (rate-limited) warning is printed to the log.
So you may see messages popping up in the form of
  "event processing lagging behind by XYZms, your system is too slow"
This is a warning only and has no immediate effect. Previously we would only
notice (and warn about) this when it affected an internal timer. Note that
these warnings do not show an issue with libinput, it shows that the the
compositor is not calling libinput_dispatch() quick enough.

The wheel tilt axis source was deprecated. No device ever had the required
udev properties set so we should stop pretending we support this.

Touchpads now support the "flat" acceleration profile. The default remains
unchanged and this needs to be selected in the configuration interface. The
"flat" profile applies a constant factor to movement deltas (1.0 for the
default speed setting).

Events from lid or tablet-mode switches that are known to libinput as being
unreliable are now filtered and no longer passed to the caller.
This prevents callers from receiving those known-bogus events and having to
replicate the same heuristics to identify unreliable devices that libinput
employs internally.

A new "libinput analyze" debugging tool is the entry tool for analysing
various aspects of devices. Right now the only tool is
"libinput analyze per-slot-delta" which can be used to detect pointer jumps
in a libiput record output. This tool used to live elsewhere, it was moved
to libinput so that reporters can easier run this tool, reducing the load on
the maintainers.

The tools have seen a few minor improvements, e.g.
- "libinput record touchpad.yml" does the right thing, no explicit --output
  argument required
- libinput measure touchpad-pressure has been revamped to be a bit more
  obvious
- libinput measure touchpad-size has been added (as replacement for the
  touchpad-edge-detector tool)
- libinput measure fuzz has been fixed to work (again and) slightly more
  reliable

The libinput test suite has been fixed to avoid interference with the
currently running session. Previously it was virtually impossible to work
while the test suite is running - multiple windows would pop up, the screen
would blank regularly, etc.

And of course a collection of fixes, quirks and new bugs.

As usual, see the git shortlog for details.
