Vertex attribute values provided via NV097_SET_VERTEX_DATA2S are
apparently two 16-bit signed integers, packed into 32 bits, which are
then to be directly mapped to floating point values in the range
[-32768.0, 32767.0].
Halo:CE uses this format to provide texture (u,v) coordinates for
render-to-texture techniques, including weapon scope, dynamic shadows,
and radar beacon--all of which are now working as expected with this
patch.
The recent fixes to xid.c (32bf810) didn't make it to xid-sdl.c. This
patch ports over those changes. In the future, the parts common to both
xid.c and xid-sdl.c should be factored out so this doesn't happen again.

* Port espes's fifo work to the split up nv2a code
This patch ports over the following commits from the XQEMU 1.x tree
(available via tag archive-xqemu-1.x) to the refactored nv2a code:
- 4d9107e8 (HEAD -> xbox, upstream/xbox) Merge branch 'fix-fifo' into xbox
- c33f4ab2 cleanups
- d3f83d93 cleanups
- faca5dd0 fix
- 7c62d7c1 fixes
- 8ad239b0 wip
- 45ed3c31 wip
- c006d5e8 wip
However, in its current form, this patch causes some regressions and
needs further investigation.
* nv2a: basic pattern object
With vga=775 on the Linux command line a first boot of the VM running
Linux works fine. After a warm reboot it crashes during Linux boot.
Before that, valgrind points out bad memory write to console
surface. The VGA code is not aware that virtio-gpu got a message
surface scanout when the display is disabled. Let's reset VGA graphic
mode when it is the case, so that a new display surface is created
when doing further VGA operations.

The code currently in gicv3_gicd_no_migration_shift_bug_post_load()
that handles migration from older QEMU versions with a particular
bug is misplaced. We need to run this after migration in all cases,
not just the cases where the "arm_gicv3/gicd_no_migration_shift_bug"
subsection is present, so it must go in a post_load hook for the
top level VMSD, not for the subsection. Move it.
