Because some VMs in QEMU can get GPU virtualization (using technologies
such as iGVT-g, as mentioned previously), they could produce a video
output that had a higher display refresh rate than of what the GTK
display was displaying. (fxp. Playing a video game inside of a Windows
VM at 60 Hz, while the output stood locked at 33 Hz because of defaults
set in include/ui/console.h)
Since QEMU does indeed have internal systems for determining frame
times as defined in ui/console.c.
The code checks for a variable called update_interval that it later
uses for time calculation. This variable, however, isn't defined
anywhere in ui/gtk.c and instead ui/console.c just sets it to
GUI_REFRESH_INTERVAL_DEFAULT which is 30
update_interval represents the number of milliseconds per display
refresh, and by doing some math we get that 1000/30 = 33.33... Hz
This creates the mentioned problem and what this patch does is that it
checks for the display refresh rate reported by GTK itself (we can take
this as a safe value) and just converts it back to a number of
milliseconds per display refresh.

Add a function to be called when a graphic update is done.
Declare the QXL renderer as async: render_update_cookie_num counts the
number of outstanding updates, and graphic_hw_update_done() is called
when it reaches none.

Fix egl_fb_read() to use the (destination) surface size instead of the
(source) framebuffer source for glReadPixels. Pass the DisplaySurface
instead of the pixeldata pointer to egl_fb_read() to make this possible.
With that in place framebuffer reads work fine even if the surface and
framebuffer sizes don't match, so we can remove the guest-triggerable
asserts in egl_scanout_flush().

In my "build everything" tree, changing sysemu/sysemu.h triggers a
recompile of some 5400 out of 6600 objects (not counting tests and
objects that don't depend on qemu/osdep.h).
Almost a third of its inclusions are actually superfluous. Delete
them. Downgrade two more to qapi/qapi-types-run-state.h, and move one
from char/serial.h to char/serial.c.
hw/semihosting/config.c, monitor/monitor.c, qdev-monitor.c, and
stubs/semihost.c define variables declared in sysemu/sysemu.h without
including it. The compiler is cool with that, but include it anyway.
This doesn't reduce actual use much, as it's still included into
widely included headers. The next commit will tackle that.

Some of the generated qapi-types-MODULE.h are included all over the

6300 qapi/qapi-builtin-types.h
5700 qapi/qapi-types-run-state.h

Clean up headers to include generated QAPI headers only where needed.
Impact is negligible except for hw/qdev-properties.h.
This header includes qapi/qapi-types-block.h and
qapi/qapi-types-misc.h. They are used only in expansions of property
definition macros such as DEFINE_PROP_BLOCKDEV_ON_ERROR() and
DEFINE_PROP_OFF_AUTO(). Moving their inclusion from
hw/qdev-properties.h to the users of these macros avoids pointless
recompiles. This is how other property definition macros, such as
DEFINE_PROP_NETDEV(), already work.
Improves things for some of the top scorers:
3600 qapi/qapi-types-common.h
2800 qapi/qapi-types-sockets.h
900 qapi/qapi-types-misc.h
2200 qapi/qapi-types-crypto.h

Now that most user interfaces are using QKeyCodes it is easier to have
common keyboard code useable by all user interfaces.
This patch adds helper code to track the state of all keyboard keys,
using a bitmap indexed by QKeyCode. Modifier state is tracked too,
as separate bitmap. That makes checking modifier state easier.
Likewise we can easily apply special handling for capslock & numlock
(toggles on keypress) and ctrl + shift (we have two keys for that).

Modern desktop environments can render icons at very large sizes,
especially with high DPI screens. Providing a 32x32 pixel bitmap is
nowhere near sufficient anymore.
When displayed in GNOME shell the QEMU icon looks awful, having been
scaled up to at least x4 its base size. This is compounded by the fact
that the BMP file doesn't do transparency, so while we've removed white
pixels, we still have anti-aliased nearly-white pixels which make the
logo look appalling on black backgrounds.
Loading a high resolution PNG icon addresses both problems, but requires
use of the extra SDL2_image library.
