I needed to debug an input configuration issue and found the debug
output not-super-helpful, so I made some improvements:
- Print the name and "sysname" (e.g. event11) of the device being
configured. Note that the name alone isn't enough since there can
be multiple identically-named devices.
- Print the config category matched for each device.
- Print the config values (if any) being applied. For enums, only the
numeric value is printed since I'm lazy.
- Don't print "pointer acceleration configured" if neither a pointer
speed nor acceleration profile is configured (it's confusing).
It is nice to have finer granularity for device types to allow for
configurations such as using `naturalScroll` on touchpads, but not on
regular pointer devices such as mice.
Made all header files to have LABWC_ prefix in include guard identifers.
Converted from __LABWC_ in 35 include/ files.
Converted from __LAB_ in 5 include/ files.
Added LABWC prefix to 3 include/ files.
Added include guards to 3 include/ files.
The double underscores were removed since according to C standard
those "are always reserved for any use".
Previously, if rc.xml defined only non-default libinput categories,
no default category was created. This meant that configure_libinput()
might totally skip configuring some devices even with default
settings, like tap-to-click.
Fix this by making sure that a default category is always created.
