virtio-gpu: do not byteswap padding
...
In Linux 5.16, the padding of struct virtio_gpu_ctrl_hdr has become a
single-byte field followed by a uint8_t[3] array of padding bytes,
and virtio_gpu_ctrl_hdr_bswap does not compile anymore.

virtio-gpu: Add virtio_gpu_set_scanout_blob
...
This API allows Qemu to set the blob allocated by the Guest as
the scanout buffer. If Opengl support is available, then the
scanout buffer would be submitted as a dmabuf to the UI; if not,
a pixman image is created from the scanout buffer and is
submitted to the UI via the display surface.

include: Make headers more self-contained
...
Back in 2016, we discussed[1] rules for headers, and these were
generally liked:
1. Have a carefully curated header that's included everywhere first. We
got that already thanks to Peter: osdep.h.
2. Headers should normally include everything they need beyond osdep.h.
If exceptions are needed for some reason, they must be documented in
the header. If all that's needed from a header is typedefs, put
those into qemu/typedefs.h instead of including the header.
3. Cyclic inclusion is forbidden.
This patch gets include/ closer to obeying 2.
It's actually extracted from my "[RFC] Baby steps towards saner
headers" series[2], which demonstrates a possible path towards
checking 2 automatically. It passes the RFC test there.
