Kills the ugly "switch (device_id) { ... }" struct and makes it easier
to figure what the differences between the uhci variants are.
Need our own DeviceClass struct for that so we can allocate some space
to store UHCIInfo.

Switching the vnc server framebuffer to use 32bpp unconditionally
turns the code bits which handle 8 and 16 bpp into dead code.
Remove them.

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.

Currently it is inconstent, PixelFormat->amask is left unset whereas
abits and amax and ashift are filled. As an alpha channel doesn't make
sense for the vga framebuffer leave all alpha fields clear.

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

Also change the way the gui_timer is initialized: each time a
displaychangelistener is registered or unregistered we'll check
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.
