[PATCH v1 0/9] gfxstream + rutabaga_gfx

[Gurchetan Singh <gurchetansingh@chromium.org>]

From: Gurchetan Singh <gurchetansingh@google.com>

Latest iteration of rutabaga_gfx + gfxstream patches.  Previous version
and more background available here:

https://patchew.org/QEMU/20230421011223.718-1-gurchetansingh@chromium.org/

Changes since RFC:
- All important memory tests pass
- Went with separate virtio-gpu-rutabaga device as suggested by Bernard
  Berschow
- Incorporated review feedback, mostly from Akihiko Odaki
- gfxstream has new unified guest/host repo + build system improvements
- added documentation on virtio-gpu
- new instructions on how to build available in the tracking bug [a]

In terms of API stability/versioning/packaging, once this series is
reviewed, the plan is to cut a "gfxstream upstream release branch".  We
will have the same API guarantees as any other QEMU project then, i.e no
breaking API changes for 5 years.

The Android Emulator will build both gfxstream (to get bug fixes fast)
and QEMU8.0+ (due to regulatory requirements) from sources.  So we haven't
created a gfxstream Debian/Ubuntu package since we actually don't need it.
Though, we plan to upload our QEMU8.0+ gfxstream enabled builds somewhere
on AOSP when it's ready.

It's more important for us to be in-tree to reduce technical debt given
this.  Let us know if there are any strong opinions on packaging.

Otherwise, feedback + reviews welcome!
