migrate_fd_cleanup will usually close the file descriptor via
buffered_file_close's call to migrate_fd_close. However, in the case
of s->file == NULL it is "inlining" migrate_fd_close (almost: there is a
direct close() instead of using s->close(s)). To fix the inconsistency
and clean up the code, allow multiple calls to migrate_fd_close and use
the function in migrate_fd_cleanup.

Now that qemu_fseek does not exist anymore, there is no reason to do
an fseek before fread/fwrite when operating on an stdio file.
Thus, unify the get/put_buffer callbacks used by qemu_fopen
with those used for pipes.

To avoid continually having to bump the initrd load address
to account for larger kernel images, put the initrd halfway
through RAM. This allows large kernels on new boards with lots
of RAM to work OK, without breaking existing usecases for
boards with only 32MB of RAM.
Note that this change fixes in passing a bug where we were
passing an overly large max_size to load_image_targphys()
for the initrd, which meant that we wouldn't correctly refuse
to load an enormous initrd that didn't actually fit into RAM.

The vnc code uses *three* DisplaySurfaces:
First is the surface of the actual QemuConsole, usually the guest
screen, but could also be a text console (monitor/serial reachable via
Ctrl-Alt-<nr> keys). This is left as-is.
Second is the current server's view of the screen content. The vnc code
uses this to figure which parts of the guest screen did _really_ change
to reduce the amount of updates sent to the vnc clients. It is also
used as data source when sending out the updates to the clients. This
surface gets replaced by a pixman image. The format changes too,
instead of using the guest screen format we'll use fixed 32bit rgb
framebuffer and convert the pixels on the fly when comparing and
updating the server framebuffer.
Third surface carries the format expected by the vnc client. That isn't
used to store image data. This surface is switched to PixelFormat and a
boolean for bigendian byte order.

With both text (curses) and graphics (vnc/sdl/spice/...) display active
vga text mode emulation fails to update both correctly. Depending on
whenever vga_update_text() or vga_draw_text() happens to be called first
only the text display or only the graphics display will see display
resolution changes and full redraws.
Fix it by calling both text/gfx resize functions in both code paths and
keep track of full screen redraws needed in VGACommonState fields.

Stop abusing displaysurface fields for text mode displays.
(bpp = 0, width = cols, height = lines).
Add flags to displaystate indicating whenever text mode display
(curses) or gfx mode displays (sdl, vnc, ...) are present.
Add separate displaychangelistener callbacks for text / gfx mode
resize & updates.
This allows to enable gfx and txt diplays at the same time and also
paves the way for more cleanups in the future.

Also change the way the gui_timer is initialized: each time a

whether we need a timer (due to dpy_refresh callback being present)
and if so setup a timer, otherwise zap it. This way the gui timer
works correctly with displaychangelisteners coming and going.

This patch adds some extra FPU state to CPUPPCState. Specifically,
fpscr is extended to a target_ulong bits, since some recent (64 bit)
CPUs now have more status bits than fit inside 32 bits. Also, we add
the 32 VSR registers present on CPUs with VSX (these extend the
standard FP regs, which together with the Altivec/VMX registers form a
64 x 128bit register file for VSX).
We don't actually support the instructions using these extra registers
in TCG yet, but we still need a place to store the state so we can
sync it with KVM and savevm/loadvm it. This patch updates the savevm
code to not fail on the extended state, but also does not actually
save it - that's a project for another patch.

Some guest operating systems' drivers (Mac OS X in particular) fail to
properly initialize the Receive Address registers (probably expecting
them to be pre-initialized by an earlier component, such as a specific
proprietary BIOS). This patch pre-initializes the RA registers, allowing
OS X networking to function properly. Other guest operating systems are
not affected, and free to (re)initialize these registers during boot.
[According to the datasheet the Address Valid bits in the RA registers
are cleared on PCI or software reset. This patch adds the NIC's MAC
address and sets Address Valid on reset. So we diverge from real
hardware behavior here. -- Stefan]

The netdev_del command crashes when given a -net device, because it
calls qemu_opts_del(NULL).
Check that this is a -netdev before attempting to delete it and the
QemuOpts.
Note the subtle change from qemu_find_opts_err("netdev", errp) to
qemu_find_opts_err("netdev", NULL). Since "netdev" is a built in
options group and we don't check for NULL return anyway, there's no use
in passing errp here.
