Rename KEYBOARD_KEY_STATE to KEY_STATE

e912d620d0f20f415b4d3dde967648e4b9c317b9 changed from POINTER_BUTTON_STATE to
simply BUTTON_STATE, replicate that for key events too.

udev: split libinput_udev context init into two functions

This is preparation work for context-specific log handlers.

Callers are now encouraged to first initialize the context with
libinput_udev_create_context() and then set the seat for this context with
libinput_udev_assign_seat().

In the upcoming patch to support context-specific log handlers this enables a
caller to set the log handler for a context before any devices are
initialized. Otherwise, a log message generated by a new device may pass a
libinput context that the caller is not yet aware of.

Change the logging system to be per-context

Rather than a single global logging function, make the logging dependent on
the individual context. This way we won't stomp on each other's feet in the
(admittedly unusual) case of having multiple libinput contexts.

The userdata argument to the log handler was dropped. The caller has a ref to
the libinput context now, any userdata can be attached to that context
instead.

Make ref count unref/ref() functions return resulting object pointer

In order to know if an unref() destroyed an object and to allow more
convenient use of ref(), make both functions return a pointer to the
object it was passed, or NULL if that object was destroyed.

Make context reference counted

Instead of only allowing one owner keeping a libinput context alive,
make context reference counted, replacing libinput_destroy() with
libinput_unref() while adding another function libinput_ref().

Even though there might not be any current use cases, it doesn't mean we
should hard code this usage model in the API. The old behaviour can be
emulated by never calling libinput_ref() while replacing
libinput_destroy() with libinput_unref().

touchpad: Avoid spurious motion event for scroll movement below threshold

If the user puts down to fingers to scroll, then changes his mind and
lifts them, without having them moved past the initial scroll threshold in
either direction, then any movement which he has done will cause a spurious
scroll event when the second finger down is lifted first.

The problem is that t->is_pointer was not being set to false in this case,
since that is done in tp_post_twofinger_scroll after checking scroll.state
which never gets set in this scenario.

Instead of changing the order, simply completely remove scroll.state completely
it is a boolean, and everywhere we check for it we also check for the axis bits
in state.direction, so it is not necessary.

Also add a check to ensure there are no spurious motion events.
