Since we have a new mechanism for requesting sizes: GtkSizeRequestIface;
it makes no sense to maintain this cache on the GtkWidget structure...
removing the requisition cache however does not break the old "size-request"
signal which is there for backwards compatability reasons.
In any case widget->requisition should not have been accessed,
gtk_widget_get_child_requisition() would have been the correct way
to consult the cache.
This commit also deprecates the newly added gtk_widget_get_requisition()
API and makes it fallback on gtk_size_request_get_size().
gdk_threads_mutex, gdk_threads_lock and gdk_threads_unlock are removed
from public API. gdk_threads_mutex was deprecated already. Instead of
using gdk_threads_lock and _unlock one was presumably supposed to use
the GDK_THREADS_ENTER and _LEAVE macros, which now simply call the
corresponding gdk_threads_enter() and _leave() functions.
Remove he dllimport/dllexport ugliness for GDK for Windows.
There is still a gdk_display variable being exported by the X11
backend.
* this mirrors the committed change for gtk_radio_action_join_group in
commit 85b53969b2
* Due to object ownership issues it is impossible to correctly use
get_group/set_group from a GI binding
* join_group is safer because at the binding level it works with individual
GtkRadioButton objects and not with the list of objects that gets
modified in the library

These members of GtkWidgetAuxData can no longer be set after
the removal of deprecated gtk_widget_set_uposition(), now removed
these members completely and removed the access to them from
gtk_widget_size_allocate().
_gtk_window_reposition() was only some extra confusing code, internally
it only calls the public API gtk_window_move()... replaced calls to
_gtk_window_reposition() with direct calls to gtk_window_move() and
removed the redundant internal API (probably there only for some historical
reason).
This recovers 10 bits, since state and saved_state as uint8 both
wasted 5 bits. Now we can add 10 more flags.
Also, a possible future patch could just do 1-bit bitfields
for the private flags instead of using manual bit twiddling.

Bug 628656 - _gdk_windowing_get_startup_notify_id memory leak
get_display_name() returns a newly allocated string, which was being fed
directory info a g_strdup_printf() call.
TrackMouseEvent is present in user32.dll in all Windows versions we
support. No need to look it up dynamically. No need to fallback to
_TrackMouseEvent from comctrl32.dll.
