These symbols (xkb_map_* and others) were replaced in xkbcommon with more
consistent names. See the header xkbcommon/xkbcommon-compat.h for how
the old names map to the new.
The new names have been available since the first stable xkbcommon
release (0.2.0).

This introduces a new struct, weston_layer_entry, which is now used
in place of wl_list to keep the link for the layer list in weston_view
and the head of the list in weston_layer.
weston_layer_entry also has a weston_layer*, which points to the layer
the view is in or, in the case the entry it's the head of the list, to
the layer itself.
The client needs to know that the pointer is at a different position in
its surface. We can't send motion as that corresponds to the pointer
actually moving. Leaving the surface and entering at the new position
is a better semantic match and doesn't correspond to pointer motion
or user input.

This was always a little iffy. At least it could have been a signal,
but we now have focus signal, so lets just use that. We lose
the ability to detect unresponsive clients at key event time, but we
could add that back by adding a key_signal.
We don't want to send events if the binding is going to handle the touch
event. Also, this restricts touch bindings to only trigger on touch down.
For gesture bindings we want something similar to the motion signal we
have for the pointer.
When we send the pointer motion event, the transform from compositor to
surface coordinates doesn't depend on the resource. Transform the
coordinates up front instead of everytime we send to a resource.
The pointer seat->keyboard was set before some possible error returns.
That pointer was left unchanged in case of failure, pointing to an
uninitialized keyboard struct (that was also leaked). If a client sent
a wl_seat::get_keyboard request, that would cause Weston to crash.
Fix this by setting the seat->keyboard pointer only after the keymap
initialization is done and there is no more possibilities for failure.
Also plug the memory leaks on the error path.

The input region of the cursor surface is set to empty in
pointer_cursor_surface_configure(). Since during the commit process
this function is called before the pending input region is made
current, it empties surface->pending.input instead of surface->input.
But pointer_cursor_surface_configure() is also called from
pointer_set_cursor() in order to map the cursor even if there isn't a
subsequent attach and commit to the cursor surface. In that case,
surface->input is never emptied, since the configure function emptied
only the pending input region and there wasn't a commit that made it
effective.
Fix this by emptying both pending and current input regions. The latter
shouldn't cause problems since the surface can't have a role prior to
being assigned the cursor role, so it shouldn't be mapped in the first
place.
Also change toytoolkit so that it triggers the bug.

Not doing this would leave a invalid list item in the view's destroy
signal listener list if destroying a seat that had previously lost
keyboard focus.

weston_xkb_info_create() takes ownership of the xkb_keymap instance so
we should drop our reference or we would leak it later if the keymap
was changed.
Previously, if a pointer was inside an output that was unplugged, it
could potentialy end up outside any valid output forever. With this
patch, the pointer is moved to the "closest" output to the pointer.
This has a couple of additional implications for the internal weston API:
1) weston_view_configure no longer exists. Use weston_view_set_position
instead.
2) The weston_surface.configure callback no longer takes a width and
height. If you need these, surface.width/height are set before
configure is called. If you need to know when the width/height
changes, you must track that yourself.
Reset pointer button count in case the driver did not emit appropriate
number of number button released events.

This removes the calls to weston_surface_buffer_width/height() from
input.c, which are the last external calls to them.
Instead, use the cached values from weston_surface::width,height. These
have already been set by weston_surface_commit(), because that is the
only way a weston_surface can get a buffer.
with the surface ref-count feature a surface may live on after its
resource was destroyed. so listen for the resource destroy signal
and set the focus to NULL.

If a view which has focus is destroyed, we would send a leave
event while changing focus, causing a segfault. Prevent this
by listening to the view's destroy signal and removing it from
the pointer focus.

Add the ability to bind to modifiers; the binding is armed when a key
which sets the requested modifier is pressed, and triggered if the key
is released with no other keys having been pressed in the meantime, as
well as mouse buttons or scroll axes.
This only works for direct modifiers (e.g. Shift and Alt), not modifiers
which latch or lock.

The signal will be emitted after the pointer is moved. A shell plugin
can listen to the signal and activate certain effects when the pointer
touches the screen corners, for instance.
A grab can potentially allocate memory and would normally end the grab
itself, freeing the allocated memory in the process. However at in some
situations the compositor may want to abort a grab. The grab owner still
needs to free some memory and abort the grab properly. To do this a new
function 'cancel' is introduced in all the grab interfaces instructing
the grabs owner to abort the grab.
This patch also hooks up grab cancelling to seat device releasing and
when the compositor looses focus, which would potentially leak memory
before.

How and when to update the keymap is left to each backend.
The new keymap only becomes effective when no keys are pressed and we
keep latched and locked modifiers from the previous state.
The weston_surface structure is split into two structures:
* The weston_surface structure storres everything required for a
client-side or server-side surface. This includes buffers; callbacks;
backend private data; input, damage, and opaque regions; and a few other
bookkeeping bits.
* The weston_view structure represents an entity in the scenegraph and
storres all of the geometry information. This includes clip region,
alpha, position, and the transformation list as well as all of the
temporary information derived from the geometry state. Because a view,
and not a surface, is a scenegraph element, the view is what is placed
in layers and planes.
There are a few things worth noting about the surface/view split:
1. This is *not* a modification to the protocol. It is, instead, a
modification to Weston's internal scenegraph to allow a single surface
to exist in multiple places at a time. Clients are completely unaware
of how many views to a particular surface exist.
2. A view is considered a direct child of a surface and is destroyed when
the surface is destroyed. Because of this, the view.surface pointer is
always valid and non-null.
3. The compositor's surface_list is replaced with a view_list. Due to
subsurfaces, building the view list is a little more complicated than
it used to be and involves building a tree of views on the fly whenever
subsurfaces are used. However, this means that backends can remain
completely subsurface-agnostic.
4. Surfaces and views both keep track of which outputs they are on.
5. The weston_surface structure now has width and height fields. These
are populated when a new buffer is attached before surface.configure
is called. This is because there are many surface-based operations
that really require the width and height and digging through the views
didn't work well.

Previously if you add a second finger while moving a window with a
touch grab then the position will keep jumping between the position of
each finger as you move them around. This patch changes it so that it
keeps track of the first touch id that starts the grab and only
updates the grab position when that finger moves.
Adds a new binding type for touch events via the new function
weston_compositor_add_touch_binding. The binding can only be added for
a touch down with the first finger. The shell now uses this to install
a binding to activate the current surface.
This fixes an uninitialized serial error, were we could send out the
modifier event even if the client didn't have a pointer resource. We
send out the modifier event to let clients know the modifer mask when
they receive a pointer button event. Thus, if the client doesn't have
a pointer we don't need to send the modifier event.
Additionally we would send out the modifier event with an
uninitialized serial number.
Finally, this commit restores the order of sending the modifier event
before the enter, like it used to be. Not likely to be an issue,
since the client will always receive the modifier event before any
button event, but it's a little nicer to give the client the modifier
events before it receives any pointer events.
Here too we must make sure the surface has a valid resource, as
there are some (xwayland, surfaces created by the shell) that
don't have it.
