default impls of width_for_height,hfw should chain directly not use wrapper API
In GtkBin and GtkWidget we tried to provide handy defaults that
call get_width if there's no get_width_for_height and
get_height for get_height_for_width.
However, they used the wrapper API on GtkSizeRequest instead of
chaining directly to the other method implementation.
This could result in all kinds of surprising behavior, for example,
get_width_for_height() would now already include the effects of set_size_request().
If nothing else it's inefficient. But it's just conceptually wrong,
because to chain to another implementation, we should call the other
implementation, not call a wrapper around the other implementation
(when we're already inside a previous invocation of the wrapper,
i.e. compute_size_for_orientation() ends up reinvoking itself
in the same orientation on the same object which it pretty
likely isn't intending to do)
32K of border ought to be enough for any pixel dimensions. At least
until screens are so huge we start using doubles.
This saves a nice 64 bits of space when we have a GtkBorder
stored somewhere.
Signed integers are used to avoid surprising unsigned math
issues. Just search GTK's whole git log from inception
for "unsigned" if you want to find any number of commits
fixing signed/unsigned bugs.

style: Fix drawing of insensitive text
When writing the original code I erroneously assumed that the current
point of the cairo context would be saved by cairo_save/restore(), but
of course the current point is part of the path and therefor isn't
saved.
Also do a cairo_new_path() before rendering any text so that we are sure
the text ends up at the right spot.
This was the last exported variable; it wasn't multihead safe,
and there's easy replacement with gdk_display_get_default().
Also drop the GDK_DISPLAY() macro which was just a wrapper around
the variable.
gtk_widget_set_window() does not add a reference to the
owned window... this is an exception to most gtk_foo_set_bar()
functions where as it acts as if it were named gtk_widget_take_window().
Adding note to the docs to avoid people giving the window to the
widget and naturally proceeding to unref the window.
Fixed issues in my previous patch for bug 626939 removing GtkRequisition
cache: these widgets monitor the previous requested size and decide whether
to queue a resize when the content changes based on it's prior request.
Now that we have a private data installed directly on
the GtkWidget instance it makes no sense to cache the size
requests on widget qdata. This change will generally make
GTK+ memory less fragmented as well as significantly speed
up the size request process.

Don't use the same name for a function that used to be a variable
Rename the gtk_major_version() etc functions I introduced yesterday to
start with gtk_get. Avoids misleading results in client programs whose
developers that don't notice the change or the compiler warnings, and
when recompiling against gtk3 then use the function addresses as the
version numbers.
With the demise of GtkList and GtkTree, it has GtkMenuItem as sole
derived class, and is not really adding any value as a separate class.
Its few useful features have been merged into GtkMenuItem.

GDK: Prefix key names with KEY_
The keysyms create a lot of potential namespace conflicts for
C, and are especially problematic for introspection, where we take
constants into the namespace, so GDK_Display conflicts with GdkDisplay.
For C application compatiblity, add gdkkeysyms-compat.h which uses
the old names.
Just one user in GTK+ continues to use gdkkeysyms-compat.h, which is
the gtkimcontextsimple.c, since porting that requires porting more
custom Perl code.

Get rid of the rest of variables exported from libgtk
Especially the gtk_*_type ones in gtktexttypes.h were mentioned in
gtk.symbols presumably by accident. That header isn't even installed,
so no way can they be supposed to be public.
gtk_text_attr_appearance_type is from the installed but "semi-private"
gtktextlayout.h, so drop that one too from gtk.symbols for now.
The use of gtk_text_unknown_char_utf8 is bit of a mess. Code in a few
files knew implicitly that it is three bytes. Define a symbolic name
for the length of it instead. Add an exported function
gtk_text_unknown_char_utf8_gtk_tests_only() that returns a pointer to
it just for the sake of gtk/tests/textbuffer.c. Prefix the variable
with an underscore.
I doubt the usefulness of the test_utf8() in textbuffer.c. If it could
be dropped, gtk_text_unknown_char_utf8_gtk_tests_only() could be
dropped, too.

Turn the gtk version and age variables into functions
Having variables exported from a DLL is slightly painful and
potentially error-prone on Windows, so let's try get rid of them now
when we can. Starting with these.
Completely removed requisition cache from GtkWidget instance structure.
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().

Remove variables from the platform-independent GDK API
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.
add gtk_radio_button_join_group method for bindings
* this mirrors the committed change for gtk_radio_action_join_group in
commit 85b53969b24d318b219663841e678943516f443a
* 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).
