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.

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.

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.

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.
