Don't try to remember the current keyboard modifier and mouse button
states from the last event, because that isn't always right, and don't
set event.state = 0 for generated events. Instead, add private functions
to get the current states, and implement them with API that retrieves
these states independently from an event.
Fixes e.g. crashs when dropping from finder.
Turn the "getting_events" boolean into a counter to handle poll_func()
being called recursively, and track the loop depth correctly by
changing its counter before bailing out in run_loop_observer_callback().
This way we reallocate our autorelease pool at the right time, and
don't kill memory that is still in use by outer run loops.
Also drain, not release the pool, just for some defensive forward
compatibility.

When an NSEvent does not have the window field set, we already assumed
the event was not for us and discarded it. But for NSMouseMoved events
we now make an exception, because such events generated after
using/clicking the main menu bar have the window field set to NULL while
the application window still has focus.
We used to experience a loss of motion events after using the menu bar,
this could be seen in buttons that stopped prelighting and first
clicks often being ignored unless you clicked somewhere else first.
These issues are fixed by this patch.
When compiled with older SDKs, the original change for this bug caused a
compiler warning about NSWindow not being able to handle a setStyleMask
message. This tricks the compiler into thinking that it can.
In 2.x, the !HAVE_XCONVERTCASE fallback of keyval_convert_case() was
implicitly used as implementation for all !X11 backends.
In 3.x, when this function was virtualized in GdkDisplayManager,
this fallback was moved to the X11 backend and the other backends
"equipped" with /* FIXME implement */ implementations of
keyval_convert_case() which don't convert anything.
Move the fallback code back to gdk/ as default implementation
of GdkDisplayManager::keyval_convert_case() and remove its
implementations is all backends but X11. Also remove the
implementation in Wayland which was a plain copy of what
is now the default implementation.

gdk_unicode_to_keyval(uc) returning (uc | 0x01000000) is not an
error return value but simply the way to encode 24-bit unicode
characters directly as keyvals.
Add enum GdkModifierIntent which identifies use cases for modifier masks
and GdkKeyMap::get_modifier_mask(). Add a default implementation which returns
what is currently hardcoded all over GTK+, and an implementation in the
quartz backend. Also add gtk_widget_get_modifier_mask() which simplifies
things by doing widget->display->keymap->get_modifier_mask().
Handle dead keys in special_ucs_table and have them converted by
UCKeyTranslate(), so all dead key combinations can be entered.
Later, this should be handled in the input method, just as it's
done for X11/Win32.
I tried to suppress compiler warnings on pre-10.6 machines this way,
but it defeats its purpose when you compile for pre-10.6 machines on
a 10.6 machine. For now, we have to live with the warnings when
compiling on/for pre-10.6 machines, there does not seem an easy and proper
way to suppress the warnings.
Normally HFS+ (the MacOSX file system) isn't case-sensitive, so having both
GtkQuartzWindow.h and gtkquartzwindow.h causes the latter to overwrite the
former during git pull, breaking the build.
