f087553653 gtk: add support for surface conversion
Also use CAIRO_FORMAT_RGB24 unconditionally.  DisplaySurfaces will never
ever see 8bpp surfaces.  And using CAIRO_FORMAT_RGB16_565 for the 16bpp
case doesn't seem to be a good idea too.

<quote src="/usr/include/cairo/cairo.h">
 * @CAIRO_FORMAT_RGB16_565: This format value is deprecated. It has
 *   never been properly implemented in cairo and should not be used
 *   by applications. (since 1.2)

030b4b7deb gtk: Fix compiler warning (GTK 3 deprecated function)
With GTK 3, the function gdk_cursor_unref is deprecated:

qemu/ui/gtk.c: In function ‘gd_cursor_define’:
qemu/ui/gtk.c:380:5: error:
 ‘gdk_cursor_unref’ is deprecated (declared at /usr/include/gtk-3.0/gdk/gdkcursor.h:233): Use 'g_object_unref' instead [-Werror=deprecated-declarations]

Fix the gcc compiler warning by using conditional compilation.

4efeabbbe8 create qemu_openpty_raw() helper function and move it to a separate file
In two places qemu uses openpty() which is very system-dependent,
and in both places the pty is switched to raw mode as well.
Make a wrapper function which does both steps, and move all the
system-dependent complexity into a separate file, together
with static/local implementations of openpty() and cfmakeraw()
from qemu-char.c.

It is in a separate file, not part of oslib-posix.c, because
openpty() often resides in -lutil which is not linked to
every program qemu builds.

This change removes #including of <pty.h>, <termios.h>
and other rather specific system headers out of qemu-common.h,
which isn't a place for such specific headers really.

This version has been verified to build correctly on Linux,
OpenBSD, FreeBSD and OpenIndiana.  On the latter it lets qemu
to be built with gtk gui which were not possible there due to
missing openpty() and cfmakeraw().

787ba4f026 gtk: implement -full-screen
Aiming for GTK as replacement for SDL, a feature like -full-screen should also
be implemented.

Bringing the window into full-screen mode is done by activating the "Fullscreen"
menu item. This is done after showing the windows to make the cursor and menu
hidden.

v2: drop -no-frame implementation, use booleans instead of ints and ensure
    consistency between ui state and menu.

bd5c51ee6c qemu-char: don't issue CHR_EVENT_OPEN in a BH
When CHR_EVENT_OPENED was initially added, it was CHR_EVENT_RESET,
and it was issued as a bottom-half:

86e94dea5b

Which we basically used to print out a greeting/prompt for the
monitor.

AFAICT the only reason this was ever done in a BH was because in
some cases we'd modify the chr_write handler for a new chardev
backend *after* the site where we issued the reset (see:
86e94d:qemu_chr_open_stdio())

At some point this event was renamed to CHR_EVENT_OPENED, and we've
maintained the use of this BH ever since.

However, due to 9f939df955, we schedule
the BH via g_idle_add(), which is causing events to sometimes be
delivered after we've already begun processing data from backends,
leading to:

 known bugs:

  QMP:
    session negotation resets with OPENED event, in some cases this
    is causing new sessions to get sporadically reset

 potential bugs:

  hw/usb/redirect.c:
    can_read handler checks for dev->parser != NULL, which may be
    true if CLOSED BH has not been executed yet. In the past, OPENED
    quiesced outstanding CLOSED events prior to us reading client
    data. If it's delayed, our check may allow reads to occur even
    though we haven't processed the OPENED event yet, and when we
    do finally get the OPENED event, our state may get reset.

  qtest.c:
    can begin session before OPENED event is processed, leading to
    a spurious reset of the system and irq_levels

  gdbstub.c:
    may start a gdb session prior to the machine being paused

To fix these, let's just drop the BH.

Since the initial reasoning for using it still applies to an extent,
work around that by deferring the delivery of CHR_EVENT_OPENED until
after the chardevs have been fully initialized, toward the end of
qmp_chardev_add() (or some cases, qemu_chr_new_from_opts()). This
defers delivery long enough that we can be assured a CharDriverState
is fully initialized before CHR_EVENT_OPENED is sent.

Also, rather than requiring each chardev to do an explicit open, do it
automatically, and allow the small few who don't desire such behavior to
suppress the OPENED-on-init behavior by setting a 'explicit_be_open'
flag.

We additionally add missing OPENED events for stdio backends on w32,
which were previously not being issued, causing us to not recieve the
banner and initial prompts for qmp/hmp.

non-NULL before registering.  This will pin the QemuConsole, so that
particular DisplayChangeListener will not follow console switches.

spice+gtk (which don't support text console input anyway) are switched
over to be pinned to console 0, which usually is the graphical display.

73d4dc71f3 gtk: suppress accelerators from the File menu when grab is active
If you're full screen, you probably expect Ctrl-Q to go to the guest,
not the host.  I think restricting certain menus is the right way to
handle this generally speaking.

c61584833c gtk: add support for screen scaling and full screen (v5)
Basic menu items to enter full screen mode and zoom in/out.  Unlike SDL, we
don't allow arbitrary scaling based on window resizing.  The current behavior
with SDL causes a lot of problems for me.

Sometimes I accidentally resize the window a tiny bit while trying to move it
(Ubuntu's 1-pixel window decorations don't help here).  After that, scaling is
now active and if the screen changes size again, badness ensues since the
aspect ratio is skewed.

Allowing zooming by 25% in and out should cover most use cases.  We can add a
more flexible scaling later but for now, I think this is a more friendly
behavior.

5104a1f650 gtk: add support for input grabbing (v2)
There is a small deviation from SDL's behavior here.  Instead of Ctrl+Alt
triggering grab, we now use Ctrl-Alt-g to trigger grab.

GTK will not accept Ctrl+Alt as an accelerator since it just consists of
modifiers.  Having grab as a proper accelerator is important as it allows a user
to override the accelerator for accessibility purposes.

We also are not automatically grabbing on left-click.  Besides the inability to
tie mouse clicks to an accelerator, I think this behavior is hard to discover
and since it only happens depending on the guest state, it can lead to confusing
behavior.

This can be changed in the future if there's a strong resistence to dropping
left-click-to-grab, but I think we're better off dropping it.

d861def367 gtk: add virtual console support (v2)
This enables VteTerminal to be used to render the text consoles.  VteTerminal is
the same widget used by gnome-terminal which means it's VT100 emulation is as
good as they come.

It's also screen reader accessible, supports copy/paste, proper scrolling and
most of the other features you would expect from a terminal widget.

a4ccabcf6d ui: add basic GTK gui (v5)
This is minimalistic and just contains the basic widget infrastructure.  The GUI
consists of a menu and a GtkNotebook.  To start with, the notebook has its tabs
hidden which provides a UI that looks very similar to SDL with the exception of
the menu bar.

The menu bar allows a user to toggle the visibility of the tabs.  Cairo is used
for rendering.

I used gtk-vnc as a reference.  gtk-vnc solves the same basic problems as QEMU
since it was originally written as a remote display for QEMU.  So for the most
part, the approach to rendering and keyboard handling should be pretty solid for
GTK.
