Adds a dedicated scroll movement type to the custom acceleration profile.
Supported by physical mouse and touchpad.
Other profiles remain the same by using the same unaccelerated filter for the scroll filter.

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.

This switches the quirk from AttrEventCodeEnable/Disable to just
AttrEventCode with a +/- prefix for each entry.
This switches the quirk from AttrInputPropEnable/Disable to just
AttrInputProp with a +/- prefix for each entry.
Previously, both event codes and input props would only apply the
last-matching section entry for a device. Furthermore, an earlier Disable entry
would take precedence over a later Enable entry. For example, a set of
sections with these lines *should* enable left, right and middle:
[first]
AttrEventCodeEnable=BTN_LEFT;BTN_RIGHT;BTN_MIDDLE
[second]
AttrEventCodeDisable=BTN_RIGHT
[third]
AttrEventCodeEnable=BTN_LEFT;BTN_RIGHT;
Alas: the first line was effectively ignored (quirks only returned the
last-matching one, i.e. the one from "third"). And due to implementation
details in evdev.c, the Disable attribute was processed after Enable,
i.e. the device was enabled for left + right and then disabled for
right. As a result, the device only had BTN_LEFT enabled.
Fix this by changing the attribute to carry both enable/disable
information and merging the commands together.
Internally, all quirks matching a device are simply ref'd into an array
in the struct quirks. The applied value is simply the last entry in the
array corresponding to our quirk.
For AttrEventCode and AttrInputProp instead do this:
- switch them to a tuple with the code as first entry and a boolean
enable/disable as second entry
- if the struct quirk already has an entry for either, append the more
recent one to the existing entry (instead of creating a new entry in
the array). This way we have all entries that match and in-order of
precedence - i.e. we can process them left-to-right to end up
with the right state.

Given that some people appear to not read until the "is not installed" part of
the error message, let's reduce the error message to just that part. This may
be confusing where a user mistypes the actual command but that happens rarely
compared to those that can't run libinput record because it's in a different

When a boolean quirk is set to "0", it is correctly disabled, but "libinput quirks list" and

This happens for example if ModelXXXX=0 is set in /etc/libinput/local-overrides.quirks, to
override a default quirk.

Scroll button locking is an accessibility feature. When enabled, the scroll
button does not need to be held down, the first click holds it logically down,
to be released on the second click of that same button.
This is implemented as simple event filter, so we still get the same behavior
from the emulated logical button, i.e. a physical double click results in a
single logical click of that button provided no scrolling was triggered.

We want to use this from the tests as well soon, so let's move it to a more
generic location. This also changes the API to be slightly more sensible, a
free() is the same cost (and safer) than passing a static buffer in and hoping
we didn't get the size wrong.

libinput applies averaging to the velocity of most pointer devices. Averaging
the velocity makes the motion look smooth and may be of benefit to bad input
devices. For good devices, however, it comes at the unfortunate price of
decreased accuaracy.
This change turns velocity averaging off by default (sets ntrackers to 2 instead
of 16) and allows for it to be turned back on via a quirk, for bad devices which
require it.
Only one place really needs the return argument, so we might as well just pass
the memory to be returned in.

The &grab pointer we used to pass as userdata was the address of the function
argument which goes out of scope at the end of the function. This works fine
for devices immediately opened but when a device connects later, the address
may have been re-used since and it's content is undefined. If not NULL, we
end up grabbing the device.
Instead pass the grab option in which is guaranteed to live until the end of
main.

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 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.
