* _gdk_device_set_associated_device() did not allow NULL device
* GdkDisplay should dispose device manager to avoid devices
trying to touch the display in finalize
* GdkDeviceManagerXI did not ref devices in id hash
* GdkDisplayX11 did not ref devices in ->input_devices
This function makes a better replacement for
gdk_display_get_core_pointer(), wherever it might yet be needed, for
XI2 resorts to XIGetClientPointer(), for the others return the only
core pointer.

This commit was created using a script that searched for all docstrings
containing a parameter and the string 'or %NULL'.
Gdk backends and demos excluded as they are not part of a public API
https://bugzilla.gnome.org/show_bug.cgi?id=610474
The Gdk-custom.c file in gir-repository contained a number of
introspection annotations. Merge those into the GDK source files.
Some documentation was moved from the tmpl/ files to accomodate
the addition of annotations.
https://bugzilla.gnome.org/show_bug.cgi?id=592279
This has two advantages:
1) In many backends, this is faster as we can terminate the window
hierarchy traversal earlier
2) When used in gdkdisplay.c::get_current_toplevel() to get the
current toplevel that has the pointer we now correctly return
a toplevel with the pointer in it where the pointer is inside
some foreign subwindow of a toplevel window.
The second advantage fixes some bugs in client side event generation
when the pointer is inside such a foreign child window.
Some applications make weird assumtions on Gtk+ that do not work anymore
with the new client-side windows support. For instance SWT/Eclipse reorders
the stacking order of the X windows directly without telling gdk this,
which breaks gdk drawing as gdk now relies on knowing the stacking order
for window clipping.
This introduces a GDK_NATIVE_WINDOWS environment variable, which if set
causes Gtk+ to always use native windows. Its more compatible with
pre-csw Gtk+ behaviour if you do weird X-specific hacks, although it does
limit the size of GdkWindows to 65535x65535.
When we ungrab the pointer we don't get enter events for the window the
pointer is in at the time of the ungrab, so we manually query for the
window the pointer is in. The same thing actually happens on re-grab if
the previous grab was !owner_events (meaning we don't get crossing events
for windows other than the grab) but the new grab is owner_events (and
thus non-grab windows need to get crossing events).
This factors out some common code and enables it also for the re-grab
to owner_events case.
If we get a nonlinear enter/leave notify on the toplevel we need
to set nonlinear in all the events we send, even if the in-toplevel
tree is linear.
This fixes combobox menus popping down immediately when you click
(not hold). (bug #587559)
we now use gdk_offscreen_window_set_embedder() instead of a signal
to get the parent. This also replaces set_has_offscreen_changes.
Rename "parent" in all embedding related names to "embedder" to make it
more obviously different than the normal parent.
Rename gdk_window_get_offscreen_pixmap to gdk_offscreen_window_get_pixmap
to match the other offscreen calls.
Rename gdk_window_offscreen_children_changed to gdk_window_geometry_changed
as this is more descriptive.
We use the offscreen signals for getting parent, picking
children at a point and mapping coordinates between windows
embedding offscreens and offscreens.
This means we have two hierarchies more or less, one visible to apps via
the standard APIs and for drawing where the offscreens are their own
separate toplevels, and another one for event handling where embedded
offscreens appear as if they were children of the embedding window.
We returned the innermost child that has the pointer, which is not right.
Only the direct child that has the pointer in it should be reported (if any).
For instance if we grab the pointer and then check if its grabbed
so that we know to ungrab we don't care that the grab is not
yet active, so report the steady state (i.e. the last grab)
The history before this was kind of twisted as several different
approaches were tested, so that was all squashed into this initial
commit to hide the uninteresting changes and files that were later
removed.

Applied patch from maemo-gtk that addresses many issues wrt
display migration and display closing (bug #85715).
* gdk/gdkdisplay.c (gdk_display_dispose): don't just set the
default display to NULL when it's closed. Instead set the most
recently opened display as new default (if one exists).
* gdk/gdkpango.c (on_renderer_display_closed): fixed signature
of this callback.
* gdk/gdkscreen.c (gdk_screen_dispose): check if the GCs still
exist before unrefing them.
* gdk/gdkwindow.c (_gdk_window_destroy_hierarchy): if the screen
is closed, allow destruction of the root window.
* gdk/x11/gdkdisplay-x11.c: moved some stuff from finalize() to
dispose(), free stuff that was leaked before.
* gdk/x11/gdkevents-x11.c (_gdk_x11_events_uninit_screen): check if
the xsettings_client still exists before destroying it.
* gdk/x11/gdkkeys-x11.c: added finalization and free the allocated
X resources.
* gdk/x11/gdkpixmap-x11.c: moved stuff from finalize() to new
dispose() implementation.
* gdk/x11/gdkscreen-x11.c: moved stuff from finalize() to
dispose() and check if it still exists before unrefing it. Set
their pointers to NULL/None *after* upchaining in dispose(),
because X11 implementations of members of the parent class still
need them for their own destruction.
* gdk/x11/gdkvisual-x11.c: removed finalize() implementation which
was g_error()ing when finalizing a visual.
* gtk/gtkclipboard.c (gtk_clipboard_finalize): don't use
get_clipboard_widget() because it would create the widget if it
doesn't exist. Use g_object_get_data() directly instead.
* gtk/gtktextdisplay.c (on_renderer_display_closed): fixed signature
of this callback.

the abi with abicheck.sh.
* gdk/gdk.symbols: New file. Definition of the GDK ABI.
