This patch adds a new API for enabling public "plugins" in libinput, in
addition to the exisitng internal ones. The API is currently limited to
specifying which paths should be loaded and whether to load them.
Public plugins are static, they are loaded before the context is initialized
and do not update after that.
If plugins are to be loaded, libinput will then run through those paths,
look up files and pass them to (future) plugins to load the actual
files.
Our debugging tools have an --enable-plugins and
--disable-plugins option that load from the default data paths
(/etc/libinput/plugins and /usr/lib{64}/libinput/plugins) and from
the $builddir/plugins directory.

The custom acceleration profile allow the user to define custom
acceleration functions for each movement type per device, giving
full control over accelerations behavior at different speeds.
This commit introduces 2 movement types which corresponds to the
2 profiles currently in use by libinput.
regular filter is Motion type.
constant filter is Fallback type.
This allows possible expansion of new movement types for the
different devices.
The custom pointer acceleration profile gives the user full control over the
acceleration behavior at different speeds.
The user needs to provide a custom acceleration function f(x) where
the x-axis is the device speed and the y-axis is the pointer speed.
The user should take into account the native device dpi and screen dpi in
order to achieve the desired behavior/feel of the acceleration.
The custom acceleration function is defined using n points which are spaced
uniformly along the x-axis, starting from 0 and continuing in constant steps.
There by the points defining the custom function are:
(0 * step, f[0]), (1 * step, f[1]), ..., ((n-1) * step, f[n-1])
where f is a list of n unitless values defining the acceleration
factor for each velocity.
When a velocity value does not lie exactly on those points, a linear
interpolation of the two closest points will be calculated.
When a velocity value is greater than the max point defined, a linear
extrapolation of the two biggest points will be calculated.

Also make the open_restricted() more robust to a NULL userdata, because

This looked good on paper but clearly no-one (including myself) ever tested this
in a real-life situation or they would've noticed that the constant factor is
missing, causing a segfault on the first two-finger scroll event, touchpad
gesture or button scrolling.
Adding the constant factor makes the API much worse and the benefit is
unclear, so out of the window it goes. We can revisit this for libinput 1.12
but this isn't going to make the next release.
This reverts commit d8bd650540.

This adds a third profile to the available profiles to map device-specific
speed to an acceleration factor, fully defined by the caller.
There has been a consistent call for different acceleration profiles in
libinput, but very little specifics in what actually needs to be changed.
"faster horses" and whatnot (some notable exceptions in e.g. bug 101139).
Attempts to change the actual acceleration function will likely break things
for others.
This approach opens up the profile itself to a user-specific acceleration
curve. A caller can set an acceleration curve by defining a number of points
on that curve to map input speed to an output factor. That factor is applied
to the input delta.
libinput does relatively little besides mapping the deltas to the
device-specific speed, querying the curve for that speed and applying that
factor. The curve is device-specific, the input speed is in device units/ms.

We had one shared parsing function for all config options so tools parse
options that don't actually make sense (e.g. --quiet or --show-keycodes for
libinput-list-devices).
This patch splits the actual libinput device configuration out and reshuffles
everything to make use of that. One large patch, because splitting this up is
more confusing than dumping it all.
This means the actual option parsing is partially duplicated between debug-gui
and debug-events but hey, not everything in life is perfect.

Chaining args together inside a single binary would be nice, but it gets nasty
quickly (as I found out adding 3, 4 extra commands). Switch over to using a
git-style exec-ing command where libinput merely changes argv[0] and then
executes whatever it assembled. And those binaries can hide in libexec so they
don't clutter up the global namespace.
This also makes it a lot easier to write man pages, adopt the same style as
git uses.
Compatibilty wrapper scripts are provided for libinput-list-devices and
libinput-debug events. These warn the user about the changed command, then
exec the new one. Expect these wrappers to be removed at some point in the
future.

There are a number of use-cases where tapping may be desirable, but
tap-and-drag is not, e.g. where tapping is used to select multiple items in a
list. Having tap-and-drag on hinders this, and the nature of the interaction
means it cannot be detected based on timeouts, movement thresholds, etc.
Provide an option instead to turn tap-an-drag off. Tap-and-drag remains
enabled by default (though tapping is disabled by default).
For the touchpad tap state diagram, the new option disables the transition
from state TOUCH to state TAPPED and releases the button immediately instead.
This means that multitap-and-drag is disabled too since we now just loop
around in the single-tap state for multitap.
It also makes tapping more responsive - we don't have to wait for the timeout
before we know whether it's a tap event. The first touch time is noted, we now
send the button press with the time of the first touch and the release with
the time of the release. This ensures a realistic time diff between the two
events.

The quartett of new config functions is:
libinput_device_config_accel_get_profiles
libinput_device_config_accel_get_profile
libinput_device_config_accel_set_profile
libinput_device_config_accel_get_default_profile
The profile defines how the pointer acceleration works, from a very high-level
perspective. Two profiles are on offer, "adaptive", the standard one we have
used so far and "flat" which is a simple multiplier of input deltas and
provides 1:1 mapping of device movement vs pointer movement.
The speed setting is on top of the profile, a speed of 0 (default) is the
equivalent to "no pointer acceleration". This is popular among gamers and
users of switchable-dpi mice.
The flat profile unnormalizes the deltas, i.e. you get what the device does
and any device below 800dpi will feel excruciatingly slow. The speed range
[-1, 1] maps into 0-200% of the speed. At 200%, a delta of 1 is translated
into a 2 pixel movement, anything higher makes it rather pointless.
The flat profile is currently available for all pointer devices but touchpads.

In some applications, notably Inkscape, where it is common to frequently drag
objects a short distance the default to drag-lock always-on is frustrating for
users.
Make it configurable, with the current default to "on".
New API:
libinput_device_config_tap_set_drag_lock_enabled
libinput_device_config_tap_get_drag_lock_enabled
libinput_device_config_tap_get_default_drag_lock_enabled
Any device capable of tapping is capable of drag lock, there is no explicit
availability check for drag lock. Configuration is independent, drag lock may
be enabled when tapping is disabled.
In the tests, enable/disable drag-lock explicitly where the tests depend
on it.

To quote Bryce Harrington from [1]:
"MIT has released software under several slightly different licenses,
including the old 'X11 License' or 'MIT License'. Some code under this
license was in fact included in X.org's Xserver in the past. However,
X.org now prefers the MIT Expat License as the standard (which,
confusingly, is also referred to as the 'MIT License'). See
http://cgit.freedesktop.org/xorg/xserver/tree/COPYING
When Wayland started, it was Kristian Høgsberg's intent to license it
compatibly with X.org. "I wanted Wayland to be usable (license-wise)
whereever X was usable." But, the text of the older X11 License was
taken for Wayland, rather than X11's current standard. This patch
corrects this by swapping in the intended text."
libinput is a fork of weston and thus inherited the original license intent
and the license boilerplate itself.
