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.

The stop variable set in the signal handler needs
volatile (and use the defined sig_atomic_t instead
of unsigned int).

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.

Now that the debug-gui is a user-visible tool, make sure the usage reflects
the right command name.

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.
