The monitor change detection code in _gdk_x11_screen_size_changed() and
process_monitors_change() goes to some length to make sure its only emitted
when there is an actual change to the data visible via the GdkScreen monitors
api.
However, commit 662e69ad added some code that always emits "monitors-changed"
in _gdk_x11_screen_size_changed when we have randr13 and get a ConfigureNotify
on the root window (even though we may already have emitted it in the
RRScreenChangesNotify event!).
As far as I can tell this is due to a comment in the bug referenced by the
commit (https://bugzilla.gnome.org/show_bug.cgi?id=601712#c4) where it says:
This version of the patch changes GdkDisplay to emit "monitors-changed" when
the primary monitor changes (see the change in _gdk_x11_screen_size_changed).
And, if you remove this part of the change the signal is not emitted when just
the primary is changed. However, this is not really the right approach. We
should just also check for if the primary changes in process_monitors_change()
to avoid spurious signal emissions.

The last paragraph still seems to be out of place though, as if it
was a previous attempt at an overview or part of some older text
elsewhere.
This overuses the passive too.
If a level 1 key maps to a key value passed to
gdk_test_simulate_key(), raise the GDK_SHIFT_MASK flag so the reqested
key value is generated. Also add a regression test for this fix.
On Windows and OS X we want to prefer the native backends over the X11
backend.
On Linux, nothing changes as nobody is going to enable those backends
(and if they do, they'll know what they get).
Previously we weren't installing the device headers when compiling
without XINPUT support. But we would include them from gdkx.h, so
essentially the build was broken.
With this patch the types will exist but not do anything.
At the same time, change the library sonames for -3.0 to just -3.
This is necessary since the 2.99 releases installed libraries like
libgtk-3.0.so.0.9903.0, and we want to prevent the library version
number from jumping back. So 3.0 will have libgtk-3.so.0.0.0.
