c6bb9ad198 qemu-img: find the image end offset during check
This patch adds the support for reporting the image end offset (in
bytes). This is particularly useful after a conversion (or a rebase)
where the destination is a block device in order to find the first
unused byte at the end of the image.

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.

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.

00e2ceae6c qom/object.c: Allow itf cast with num_itfs = 0
num_interfaces only tells you how many interfaces the concrete child class has
(as defined in the TypeInfo). This means if you have a child class which defines
no interfaces of its own, but its parent has interfaces you cannot cast to those
parent interfaces.

Fixed changing the guard to check the class->interfaces list instead (which is
a complete flattened list of implemented interfaces).

3e407de477 qom/object.c: Reset interface list on inheritance
The QOM framework will attempt the recreate a classes interface list from
scratch for each class. This means that a child class should zero out the
list of interfaces when cloned from the parent class.

Currently the list is memcpy()d from the parent to the child. As the interface
list is just a pointer to a list, this means the parent and child will share
the same list of interfaces. When the child inits, it will append its own
interfaces to the parents list. This is incorrect as the parent should not pick
up its childs interfaces.

This actually causes an infinite loop at class init time, as the child will
iterate through the parent interface list adding each itf to its own list(in
type_initialize()). As the list is (erroneously) shared, the new interface
instances for the child are appended to the parent, and the iterator never hits
the tail and loops forever.

b1424e0381 vga: fix byteswapping.
In case host and guest endianness differ the vga code first creates
a shared surface (using qemu_create_displaysurface_from), then goes
patch the surface format to indicate that the bytes must be swapped.

The switch to pixman broke that hack as the format patching isn't
propagated into the pixman image, so ui code using the pixman image
directly (such as vnc) uses the wrong format.

Fix that by adding a byteswap parameter to
qemu_create_displaysurface_from, so we'll use the correct format
when creating the surface (and the pixman image) and don't have
to patch the format afterwards.

8917c3bdba slirp: switch to GPollFD
Slirp uses rfds/wfds/xfds more extensively than other QEMU components.

The rarely-used out-of-band TCP data feature is used.  That means we
need the full table of select(2) to g_poll(3) events:

  rfds -> G_IO_IN | G_IO_HUP | G_IO_ERR
  wfds -> G_IO_OUT | G_IO_ERR
  xfds -> G_IO_PRI

I came up with this table by looking at Linux fs/select.c which maps
select(2) to poll(2) internally.

Another detail to watch out for are the global variables that reference
rfds/wfds/xfds during slirp_select_poll().  sofcantrcvmore() and
sofcantsendmore() use these globals to clear fd_set bits.  When
sofcantrcvmore() is called, the wfds bit is cleared so that the write
handler will no longer be run for this iteration of the event loop.

This actually seems buggy to me since TCP connections can be half-closed
and we'd still want to handle data in half-duplex fashion.  I think the
real intention is to avoid running the read/write handler when the
socket has been fully closed.  This is indicated with the SS_NOFDREF
state bit so we now check for it before invoking the TCP write handler.
Note that UDP/ICMP code paths don't care because they are
connectionless.

Note that slirp/ has a lot of tabs and sometimes mixed tabs with spaces.
I followed the style of the surrounding code.

cbff4b342b main-loop: switch to g_poll() on POSIX hosts
Use g_poll(3) instead of select(2).  Well, this is kind of a cheat.
It's true that we're now using g_poll(3) on POSIX hosts but the *_fill()
and *_poll() functions are still using rfds/wfds/xfds.

We've set the scene to start converting *_fill() and *_poll() functions
step-by-step until no more rfds/wfds/xfds users remain.  Then we'll drop
the temporary gpollfds_from_select() and gpollfds_to_select() functions
and be left with native g_poll(2).

On Windows things are a little crazy: convert from rfds/wfds/xfds to
GPollFDs, back to rfds/wfds/xfds, call select(2), rfds/wfds/xfds back to
GPollFDs, and finally back to rfds/wfds/xfds again.  This is only
temporary and keeps the Windows build working through the following
patches.  We'll drop this excessive conversion later and be left with a
single GPollFDs -> select(2) -> GPollFDs sequence that allows Windows to
use select(2) while the rest of QEMU only knows about GPollFD.

with qemu-system-ppc -M bamboo -kernel $kernel -initrd $ramdisk -m 512, but QEMU
would just hang. However, when I used -m 256, the machine would boot.

I looked through the code in hw/ and it seems there is an error when the
RAM memory is setup (if my understanding is correct).

After patching it, the machine launched and booted successfully with 512MB of
RAM.

e2f515cf2f target-i386: Discard CC_OP computation in set_cc_op also
The shift and rotate insns use movcond to set CC_OP, and thus
achieve a conditional EFLAGS setting.  By discarding CC_OP in
a later flags setting insn, we can discard that movcond.
