c5d4dac86b virtio-vga: add virtio gpu device with vga compatibility
This patch adds a virtio-vga device.  It is simliar to virtio-gpu-pci,
but it also adds in vga compatibility, so guests without native
virtio-gpu support can drive the device in vga mode.  It is compatible
with stdvga.

c3b1060514 vga: Add endian to vmstate
Include the endian state in the migration stream as an optional
subsection which we only include when the endian isn't the default,
thus enabling backward compatibility of the common case.

Signed-off-by: Benjamin Herrenschmidt <benh@kernel.crashing.org>

Changes by kraxel:
 * Remove bochs dispi interface changes.  We'll do that in
   a different way to make sure we don't conflict with
   possible future bochs dispi interface changes.
 * keep live migration bits.

54a85d4624 vbe: make bochs dispi interface return the correct memory size with qxl
VgaState->vram_size is the size of the pci bar.  In case of qxl not the
whole pci bar can be used as vga framebuffer.  Add a new variable
vbe_size to handle that case.  By default (if unset) it equals
vram_size, but qxl can set vbe_size to something else.

This makes sure VBE_DISPI_INDEX_VIDEO_MEMORY_64K returns correct results
and sanity checks are done with the correct size too.

ad37168cbd vga: do not dynamically allocate chain4_alias
Instead, add a boolean variable to indicate the presence of the region.
This avoids a repeated malloc/free (later we can also avoid the
add_child/unparent by changing the offset/size of the alias).

848696bf35 PortioList: Store PortioList in device state
PortioList is an abstraction used for construction of MemoryRegionPortioList
from MemoryRegionPortio. It can be used later to unmap created memory regions.
It also requires proper cleanup because some of the memory inside is allocated
dynamically.

By moving PortioList ot device state we make it possible to cleanup later and
avoid leaking memory.

This change spans several target platforms.  The following testcases cover all
changed lines:
  qemu-system-ppc -M prep
  qemu-system-i386 -vga qxl
  qemu-system-i386 -M isapc -soundhw adlib -device ib700,id=watchdog0,bus=isa.0

2c62f08ddb console: simplify screendump
Screendumps are alot simpler as we can update non-active
QemuConsoles now.  So we only need to update the QemuConsole
we want write out, then dump the DisplaySurface content into
a ppm file.  Done.

No console switching needed.  No special support code in the
gfx card emulation needed.  Zap it all.  Also move ppm_save
out of the vga code and next to the qmp_screendump function.

For now screen dumping is limited to console #0 (like it used
to be), even though it is dead simple to extend it to other
consoles.  I wanna finish the console cleanup before setting
new qapi interfaces into stone.

1dbfa00503 console: rename vga_hw_*, add QemuConsole param
Add QemuConsole parameter to vga_hw_*, so the interface allows to update
non-active consoles (the actual code can't handle this yet, see next
patch).  Passing NULL is allowed and updates the active console, like
the functions do today.

While touching all vga_hw_* calls anyway rename that to the functions to
hardware-neutral graphics_hw_*
