Move to virtio-gpu-3d.c where all the other virgl code lives too.

This patch makes virtio-gpu track host memory allocations for ressources
and applies a limit (configurable 256M by default). When exceeding the
limit virtio-gpu throws VIRTIO_GPU_RESP_ERR_OUT_OF_MEMORY errors (like
it already does today when pixman image allocations fail).
This patch covers 2d mode only. For 3d mode we have to figure how we
are going to handle this best. qemu doesn't track resources in case
virglrenderer is used, so I guess we should extend virglrenderer to
allow setting a limit, then let qemu set the limit and catch
virgl_renderer_resource_create failures.

The virtio-gpu.h file defines a macro VIRTIO_GPU_FILL_CMD
which includes a call to qemu_log_mask, but does not
include qemu/log.h. In a default configure, it is lucky
and gets qemu/log.h indirectly due to the 'log' trace
backend being enabled. If that trace backend is disabled
though, eg
./configure --enable-trace-backends=nop
Then the build will fail:

virgl conditionally registers a vmstate as unmigratable when virgl
is enabled; instead use the migrate_add_blocker mechanism.

Header guard symbols should match their file name to make guard
collisions less likely. Offenders found with
scripts/clean-header-guards.pl -vn.
Cleaned up with scripts/clean-header-guards.pl, followed by some
renaming of new guard symbols picked by the script to better ones.

In virgl_cmd_resource_flush(), when several consoles are updated, it
needs to keep blocking until all spice gl draws are done. This fixes an
assert() in spice when using multiple monitors with virgl.

Store some additional state for cursor and resource backing storage,
so we can write out and reload things. Implement vmsave+vmload for
2d mode. Continue blocking live migration in 3d/virgl mode.

We'll go take out the commands we receive out of the virt queue and put
them into a linked list, to decouple virtio queue handling from actual
command processing.
Also move cmd processing to new virtio_gpu_handle_ctrl func, so we can
easily kick it from different places.

Switch over to virtio_instance_init_common. Drop duplicate properties
in virtio-gpu-pci and virtio-vga as they are properly aliased now. Also
drop the indirection via DEFINE_VIRTIO_GPU_PROPERTIES, we don't need it
any more as the properties are defined in a single place now.
