58ea90f803 ui/gtk: set scanout mode in gd_egl/gd_gl_area_scanout_texture
Fixing a regression (black screen) caused by a commit 92b58156e7
("ui/gtk: set scanout-mode right before scheduling draw").

The commit 92b58156e7 was made with an assumption that the scanout
mode needs to be set only if the guest scanout is a dmabuf but there
are cases (e.g. virtio-gpu-virgl) where the scanout is still processed
in a form of a texture but is not backed by dmabuf. So it is needed
to put back the line that sets scanout mode in gd_egl_scanout_texture
and gd_gl_area_scanout_texture.

92b58156e7 ui/gtk: set scanout-mode right before scheduling draw
Setting scanout mode is better to be done very last minute
right because the mode can be reset anytime after it is set in
dpy_gl_scanout_texture by any asynchronouse dpy_refresh call,
which eventually cancels drawing of the guest scanout texture.

whole surface (e.g. guest's Xorg extended display). Then use
'width' and 'height' for sub region in there (e.g. guest's
scanouts).

0d0be87659 virtio-gpu: replace the surface with null surface when resetting
The primary guest scanout shows the booting screen right after reboot
but additional guest displays (i.e. max_ouptuts > 1) will keep displaying
the old frames until the guest virtio gpu driver gets initialized, which
could cause some confusion. A better way is to to replace the surface with
a place holder that tells the display is not active during the reset of
virtio-gpu device.

And to immediately update the surface with the place holder image after
the switch, displaychangelistener_gfx_switch needs to be called with
'update == TRUE' in dpy_gfx_replace_surface when the new surface is NULL.

D-Bus doesn't support fd-passing on Windows (AF_UNIX doesn't have
SCM_RIGHTS yet, but there are other means to share objects. I have
proposed various solutions upstream, but none seem fitting enough atm).

To make the "-display dbus" work on Windows, implement an alternative
D-Bus interface where all the 'h' (FDs) arguments are replaced with
'ay' (WSASocketW data), and sockets are passed to the other end via
WSADuplicateSocket().

bd1386cce1 cutils: Adjust signature of parse_uint[_full]
It's already confusing that we have two very similar functions for
wrapping the parse of a 64-bit unsigned value, differing mainly on
whether they permit leading '-'.  Adjust the signature of parse_uint()
and parse_uint_full() to be like all of qemu_strto*(): put the result
parameter last, use the same types (uint64_t and unsigned long long
have the same width, but are not always the same type), and mark
endptr const (this latter change only affects the rare caller of
parse_uint).  Adjust all callers in the tree.

While at it, note that since cutils.c already includes:

    QEMU_BUILD_BUG_ON(sizeof(int64_t) != sizeof(long long));

we are guaranteed that the result of parse_uint* cannot exceed
UINT64_MAX (or the build would have failed), so we can drop
pre-existing dead comparisons in opts-visitor.c that were never false.

5a4cb61ae1 ui/gtk: enable backend to send multi-touch events
GTK3 provides the infrastructure to receive and process multi-touch
events through the "touch-event" signal and the GdkEventTouch type.
Make use of it to transpose events from the host to the guest.

This allows users of machines with hardware capable of receiving
multi-touch events to run guests that can also receive those events
and interpret them as gestures, when appropriate.

An example of this in action can be seen here:

4c93ce54e7 ui/cursor: make width/height unsigned 16-bit integer
Although not actually exploitable at the moment, a negative width/height
could make datasize wrap around and potentially lead to buffer overflow.
Since there is no reason a negative width/height is ever appropriate,
modify QEMUCursor struct and cursor_alloc prototype to accept uint16_t.
This protects us against accidentally introducing future bugs.

1dfea3f212 ui/sdl2: disable SDL_HINT_GRAB_KEYBOARD on Windows
Windows sends an extra left control key up/down input event for
every right alt key up/down input event for keyboards with
international layout. Since commit 830473455f ("ui/sdl2: fix
handling of AltGr key on Windows") QEMU uses a Windows low level
keyboard hook procedure to reliably filter out the special left
control key and to grab the keyboard on Windows.

The SDL2 version 2.0.16 introduced its own Windows low level
keyboard hook procedure to grab the keyboard. Windows calls this
callback before the QEMU keyboard hook procedure. This disables
the special left control key filter when the keyboard is grabbed.

To fix the problem, disable the SDL2 Windows low level keyboard
hook procedure.

083db9db44 ui/sdl2: Grab Alt+F4 also under Windows
SDL doesn't grab Alt+F4 under Windows by default. Pressing Alt+F4 thus closes
the VM immediately without confirmation, possibly leading to data loss. Fix
this by always grabbing Alt+F4 on Windows hosts, too.

efc00a3709 ui/sdl2: Grab Alt+Tab also in fullscreen mode
By default, SDL grabs Alt+Tab only in non-fullscreen mode. This causes Alt+Tab
to switch tasks on the host rather than in the VM in fullscreen mode while it
switches tasks in non-fullscreen mode in the VM. Fix this confusing behavior
by grabbing Alt+Tab in fullscreen mode, always causing tasks to be switched in
the VM.
