3ea32d1355 vhost-user-gpu: abstract vg_cleanup_mapping_iov
Currently in vhost-user-gpu, we free resource directly in
the cleanup case of resource. If we change the cleanup logic
we need to change several places, also abstruct a
'vg_create_mapping_iov' can be symmetry with the
'vg_create_mapping_iov'. This is like what virtio-gpu does,
no function changed.

1f83ea8dbd vhost-user-gpu: handle vhost-user-gpu features in a callback
Fixes a deadlock where the backend calls QEMU, while QEMU also calls the
backend simultaneously, both ends waiting for each other.

4bd802b209 Clean up includes
Clean up includes so that osdep.h is included first and headers
which it implies are not included manually.

This commit was created with scripts/clean-includes, with the changes
to the following files manually reverted:

contrib/plugins/, tests/plugin/, and tests/test-rcu-slist.c appear not
to include osdep.h intentionally.  The remaining reverts are the same
as in commit bbfff19688.

0df750e9d3 libvhost-user: make it a meson subproject
By making libvhost-user a subproject, check it builds
standalone (without the global QEMU cflags etc).

Note that the library still relies on QEMU include/qemu/atomic.h and
linux_headers/.

d52c454aad contrib: add vhost-user-gpu
Add a vhost-user gpu backend, based on virtio-gpu/3d device. It is
associated with a vhost-user-gpu device.

Various TODO and nice to have items:
