When it comes to a window frame, a tablet tool and cursor act almost
identical; they click things, drag things, etc. The tool type and extra
axes don't serve any use in the context of a window frame, so tablet
pointers share the frame_pointer structures used for the mouse pointer.

The tablet is given a separate cursor. Most tablet interaction is an absolute
interaction and shouldn't need a cursor at all, but usually the cursor is used
to indicate the type of virtual tool currently assigned.

Introduces three new structs, weston_tablet and weston_tablet_tool for the
respective devices, with the respective information as it's used on the protocol.
And weston_tablet_tool_id to track the tools of a tablet.
Note that tools are independent of tablets, many tools can be used across
multiple tablets.
The nesting on the protocol level requires a global tablet manager, a tablet
seat nested into weston_seat. The list of tablets and tools are also part of
the weston_seat.
Most functions are stubs except for the actual tablet and tablet tool
creation and removal.
This is based on patches from Peter Hutterer <peter.hutterer@who-t.net> and

We need only check that the region is not empty. If either the input region or
the constraint region have degenerate extents, the intersection from the
previous instruction will set confine_region->data to pixman_region_empty_data.

Since the logic of pointer constraints assumes a valid view throughout, add a
signal to disable constraints when its current view is unmapped by Weston.
The assumption that a previously unmapped view is valid already leads to the
constraints code crashing. This can happen when attaching a NULL buffer to the
surface and commiting, which effectively unmaps the view with the side effect of
clearing the surface's input region, which is then assumed valid inside
maybe_warp_confined_pointer().

Push weston_coord into the notification functions instead of passing
two doubles.
The touch handlers are passed a pointer to a weston_coord, which is
unusual. This is done so we can pass a NULL pointer instead of a
fabricated invalid coordinate when the touch type is TOUCH_UP.

When the pointer is confined and we are handling motion, we need
up-to-date view transforms in order to respect the confinement. So
update view transforms in such case.

When the pointer is constrained and the surface in which it is
constrained gets committed, we may warp the pointer in some
circumstances. In order to do that, we need the associated view
transforms up-to-date. So update view transforms when this surface gets
committed.
This fixes an issue in which we'd hit an assert when trying to warp the
pointer, as we were trying to transform views with dirty transforms.

There are two problems here, one is that the surface jump logic only makes
sense if the view remains the same.
The more important fix is that pointer coordinates are in global coordinates
and we want view coordinates, so this test was always wrong and led to an
xdg ping storm due to spurious focus changes.

Whether these coordinates are "invalid" (set to an unlikely sentinel value)
or not is based purely on whether pointer->view is valid.
Check pointer->view before using these values every time, and stop
using an "invalid" value entirely.
The reason for this is that in the future we're reworking how 2D
coordinates are handled, and removing the dubious conecept of an invalid
coordinate simplifies things a little.

sx and sy are meaningless (-1000000) when view is NULL. The case this
is meant to catch is when the surface coordinates change while the
global coordinate doesn't, (eg: max/unmax a window with a keyboard

This lets us say what we really mean instead of passing a NULL output

Currently the frame event gets lost: The touch focus is removed in the 'up'
event. So the focus is gone when the frame event arrives so it is never sent to
the clients.
To avoid this, keep the touch focus until the frame is handled.

This is arguably a little nicer without calling the pixman functions
directly.
In the future when we have different datatypes for coordinates in different
spaces, this test will only be valid on global coordinates, so this change
is also a precursor to stronger type validation.

Tracking correctly previous events shouldn't corrupt the surface destroy
signal list. This enforces that by ensuring that we wouldn't have
a .notify wl_listener still being set (which shouldn't happen if we do
eventually get a focus_in event that clears it out).

We also need to push the idle inhibition counting after that early

If two or more clients were running and the one that was focused when
weston itself lost keyboard focus was killed, weston would crash.
This is because commit 85d55540cb changed the way we handle saved keyboard
focus when we lose focus, and did so in such a way that the saved keyboard
focus listener could be removed from the surface destroy signal list
during the emit of the surface destroy signal. This corrupted the list
and led to a NULL pointer dereference.
Fix this by using a boolean flag to determine whether we should obey the
saved keyboard focus. We can set this safely in cases where
removing the listener would cause a crash.

And ultimately, fail to start when there are no input devices on the
system. Patchs adds consistency to touch/pointer initialization to
return -1 in case same thing happens.
Further more, when the device is not created we can't assume to retrieve
a valid one from a libinput_device so guard against it. This takes care of
hot-plugging situations when we couldn't create the (keyboard) device,
or when removing it.

When setting a cursor surface, use the surface dimensions, instead of the
weston_surface buffer reference, to check if the surface has any
content. A weston_surface without any buffer reference may in fact
have a buffer which was committed in a previous pointer entry, dropped
by weston_surface and now held only internally by the renderer.
Without this fix, when a pointer enters a surface, the cursor image is
not correctly updated if we set a cursor surface with an already
committed buffer from a previous pointer entry, without recommitting the
cursor buffer for the current entry. This can be seen, for example, in
the experimental Wine Wayland driver which handles the cursor in a way
that leads to the following scenario:
Setup: cursor_surface.attach(buffer) & cursor_surface.commit()
On first wl_pointer.enter: pointer.set_cursor(cursor_surface)
compositor/renderer redraws
wl_pointer.leave
On second wl_pointer.enter: pointer.set_cursor(cursor_surface)
When handling the second pointer.set_cursor() request the current code
doesn't find a buffer attached to the cursor_surface (only the renderer
now has a reference to it), so it doesn't update the respective view for
the cursor.
