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).
This is a common practice in C projects, which simply enforces that
each header must compile cleanly without implicit dependencies on
other headers (see also the previous commit).
This revises the changes done in 22d319c:
- Cancel defaulting to <dragLock>sticky<dragLock>. So labwc now disables
drag-lock by default, as libinput does.
- Update the options from [yes|no|sticky] to [timeout|no|yes] to
emphasize that the "sticky" mode (now "yes") is recommended when using
drag-lock.
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.
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.
