This part of the copyright blurb stems from the GPL use recommendations:
https://www.gnu.org/licenses/gpl-howto.en.html
The concept appears to originate in times where version control was per
file, instead of per tree, and was a way to glue the files together.
Ultimately, we nowadays don't live in that world anymore, and this
information is entirely useless anyway, as people are very welcome to
copy these files into any projects they like, and they shouldn't have to
change bits that are part of our copyright header for that.
hence, let's just get rid of this old cruft, and shorten our codebase a
bit.
The input_id builtin assigns the various ID_INPUT based on the exported evdev
bits. In some cases, the device may not have the properties required to label
a device as one specific type but the physical form factor is clear.
e.g. in the case of #7197 it's a tablet pad that does not have x/y axes which
the kernel exports for pads for historical reasons.
A custom override is needed, best to be solved with a hwdb entry.

When the joystick is integrated directly into the machine, knowing
that the device is internal allows us to disable attached functionality
when the device is not used or inaccessible.
For example, this allows disabling rumble and accelerometer on
flip-console-like devices like the GPD-XD.
This is useful on systems like NixOS, where python3 is not in
/usr/bin/python3 as well as for people using alternative ways to
install python such as virtualenv/pyenv.
It is useful for desktop environments to be able to show Caps-Lock or
Num-Lock status changes as an on-screen display when using a keyboard
that doesn't have LEDs for this.
Closes: #5559
Plenty of single scroll-wheel mice have the ability to tilt the wheel to
generate horizontal wheel events. They use the same evdev axis as a real
horizontal wheel (REL_HWHEEL) and are indistinguishable to userspace from the
real thing. libinput promises physical degrees for wheel events but that's not
accurate for those tilting wheels, hence mark them as tilting wheels so we can
treat them like the special snowflakes they think they are.
We would catch stuff like:
ACCEL_MOUNT_MATRIX=0, -1, 0; -1, 0, 0; 0, 0.0., 0
but not
ACCEL_MOUNT_MATRIX=0, -1, 0; -1, 0, 0; 0, 0, 0.0.
because the match would stop at the next-to-last char. Fix that
by requiring a line end.
Yubikeys and other pseudo keyboards require that they are in the US layout,
otherwise the data they send is invalid. Add two new keys to signal this to
processes that handles (XKB) layouts.
pyparsing uses the system locale by default, which in the case of 'C' (in lots
of build environment) will fail with a UnicodeDecodeError. Explicitly open it
with UTF-8 encoding to guard against this.
pyparsing 2.1.10 fixed the handling of LineStart to really just apply to line
starts and not ignore whitespace and comments any more. Adjust EMPTYLINE to
this.
Many thanks to Paul McGuire for pointing this out!

MOUSE_WHEEL_CLICK_ANGLE has been an integer, and at least libinput (probably
the only user) parses it as strict integer. For backwards compatibility, we
cannot change it to a decimal number now.
Add a new property to list the number of clicks for a full 360 degree
rotation, to be specified in addition to the old click angle property. Clients
can prefer the new one where available and calculate the decimal value to
whatever precision they want.
This parser will also be used in libinput, which uses the MIT license, so
relicense this file to the more permissive license to make bidirectional code
flow easier. parse_hwdb.py is only useful during building of the project, and
is not part of the installation, so effectively both licenses are very similar.
In particular, the licensing of binary packages produced by systemd is not
influenced in any way, because the MIT licensed part is not installed.
The Logitech MX Master has a horizontal scroll wheel with a different click
angle than the vertical one. Add a new property for this case, we can't add
values to the normal one without risking upsetting existing parsers.
Fixes#3947
This works for hwdb/[67]0-*.hwdb. I also added code to parse hwdb/20-*, but those
files are huge, and parsing them using this parser is annoyingly slow (about one
minute for the biggest files). So I removed the support for hwdb/20-*, a much simpler
hand-generated parser should suffice for those.
