From: Volker Rümelin <vr_qemu@t-online.de>

Import win32 keyboard hooking code from project spice-gtk. This
patch removes the extra left control key up/down input events
inserted by Windows for the right alt key up/down input events
with international keyboard layouts. Additionally there's some
code to grab the keyboard.

The next patches will use this code.

Only Windows needs this.

There is no way to grab the Ctrl-Alt-Del key combination on
Windows. This key combination will leave all three keys in a
stuck condition. This patch uses the grab-broken-event to
release the keys.

From: Volker Rümelin <vr_qemu@t-online.de>

Since the removal of GTK2 code in commit 89d85cde75 the code
around ignore_keys is unused. See commit 1a01716a30 "gtk: Avoid
accel key leakage into guest on console switch" why it was only
needed for GTK2.

From: Volker Rümelin <vr_qemu@t-online.de>

QEMU with SDL 1.2 display used to enable keyboard and mouse grab-
bing when started in full screen. The SDL 2.0 code tries to do
the same but fails to enable grabbing because sdl_grab_start(0)
returns early. To do it's work the sdl_grab_start() function
needs a pointer to a sdl2_console structure.

From: Volker Rümelin <vr_qemu@t-online.de>

Without keyboard grab Windows currently handles the two win keys
and the key events are also sent to the guest. This is undesir-
able. Only one program should handle key events. This patch ap-
plies commit c68f74b02e "win32: do not handle win keys when the
keyboard is not grabbed" from project spice-gtk to ui/gtk.c to
fix this problem.

From: Volker Rümelin <vr_qemu@t-online.de>

Since GTK 3.22 the function gdk_event_get_scancode() is
available. On Windows this function returns keyboard scancodes
and some extended flags. These raw keyboard scancodes are much
better suited for this use case than the half-cooked win32
virtual-key codes because scancodes report the key position on
the keyboard and the positions are independent of national
language settings.

Based on a mail on the qemu-devel mailing list at
https://lists.nongnu.org/archive/html/qemu-devel/2020-05/msg02909.html
and some internet research the GTK3 versions on supported
platforms are:

    RHEL-7.4: 3.22.10
    RHEL-7.5: 3.22.26
    Debian (Stretch): 3.22.11
    Debian (Buster): 3.24.5
    OpenBSD (Ports): 3.22.30
    FreeBSD (Ports): 3.22.29
    OpenSUSE Leap 15: 3.22.30
    SLE12-SP2: Unknown
    SLE15: 3.22.30
    Ubuntu (Bionic): 3.22.30
    Ubuntu (Focal): 3.24.18
    macOS (Homebrew): 3.22.30

This justifies increasing the minimum required GTK version in
QEMU to 3.22.0.

This patch content doesn't match exactly the content of the message-id.

There are some build-sys changes.

If we limit this object compilation, shouldn't we also limit the stub?
