Before 176e3783f2 (ui/sdl2: OpenGL window context)
SDL_CreateRenderer was called unconditionally setting
the swap interval to 0. Since SDL_CreateRenderer is now no
longer called when OpenGL is enabled, the swap interval is
no longer set explicitly and vsync handling depends on
the environment settings which may lead to a performance
regression with virgl as reported in
https://gitlab.com/qemu-project/qemu/-/issues/2565
Restore the old vsync handling by explicitly calling
SDL_GL_SetSwapInterval if OpenGL is enabled.

Ignore GUI keys for SDL_TEXTINPUT events, just like GUI keys are
ignored for SDL_KEYDOWN events. This prevents unintended text input
in a text console when hiding the text console with the GUI keys.
The SDL_TEXTINPUT event always comes after the SDL_KEYDOWN event.
See https://github.com/libsdl-org/SDL/issues/1659.

Each virtual console in the SDL2 frontend has a key state map.
When switching windows with GUI keys we have to release all
pressed modifier keys in the currently active window, because
after the switch the now inactive window no longer receives the
key release events.
To reproduce the issue open a text editor in the SDL UI and then
press Ctrl-Alt-2 to open a Compat Monitor Console. Close the
console with the mouse. Try to enter text in the text editor and
notice that the modifier keys Ctrl and Alt are stuck and need to
be pressed once to be released.

Previously, when using the SDL2 UI on MacOS, the title bar uses incorrect
key names (such as Ctrl and Alt instead of the standard MacOS key symbols
like ⌃ and ⌥). This commit changes sdl_update_caption in ui/sdl2.c to
use the correct symbols when compiling for MacOS (CONFIG_DARWIN is
defined).
Unfortunately, standard Mac keyboards do not include a "Right-Ctrl" key,
so in the case that the SDL grab mode is set to HOT_KEY_MOD_RCTRL, the
default text is still used.

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.

This workaround was put in place in the original implementation almost
10 years ago, considering a very old SDL2 version. Currently it prevents
users to run in a wayland-only environment without manually forcing the
backend.
The SDL2 wayland backend has been supported by distributions for a very
long time (e.g. in Fedora, first available 8 years ago), and is now
considered stable and becoming the default for new SDL2 releases.
Instead of requiring the x11 backend to exist by default, let new qemu
releases run with the default chosen by the installed SDL2 version.

This introduces the new "DisplaySDL" QAPI struct that is used to hold

objects (not counting tests and objects that don't depend on
qemu/osdep.h, down from 5400 due to the previous two commits).
* It pulls in more than a dozen additional headers.
Split stuff related to run state management into its own header
sysemu/runstate.h.
Touching sysemu/sysemu.h now recompiles some 850 objects. qemu/uuid.h

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

Pre-rendered icons are provided at the standard sizes expected for GUI
applications, along with the scalable SVG, to ensure maximum portability.
The PNGs are rendered from the SVG using inkscape, however, this is not
