They're not supported yet so let's not pretend they are.
In particular use_local_buffers can cause VM_ALWAYS_VALID to be
used, which then prevents the creation of a dmabuf.

Native context support is implemented by diverting the libdrm_amdgpu functions
into new functions that use virtio-gpu.
VA allocations are done directly in the guest, using newly exposed libdrm_amdgpu
helpers (retrieved through dlopen/dlsym).
Guest <-> Host roundtrips can be expensive so we try to avoid them as much as
possible. When possible we also don't wait for the host reply in case where
it's not needed to get correct result.
Implicit sync works because virtio-gpu commands are submitted in order to the
host (there a single queue per device, shared by all the guest processes).
virtio-gpu also only supports one context per file description (but multiple
file descriptions per process) while amdgpu only allows one fd per process,
but multiple contexts per fd. This causes synchronization problems, because
virtio-gpu drops all sync primitive if they belong to the same fd/context/ring:
ie the amdgpu_ctx can't be expressed in virtio-gpu terms.
For now the solution is to only allocate a single amdgpu_ctx per application.
Contrary to radeonsi/radv, amdgpu_virtio can use libdrm_amdgpu directly: the
ones that don't rely on ioctl() are safe to use here.

This is required to implement virtio native-context.
In a virtualized environment, most of the functions provided
by libdrm_amdgpu will be implemented using virtio.
This allows to implement efficient virtualization, by
forwarding the kernel API to the host, instead of the GL/VK calls.
Similarly, the raw 'fd' or 'gem_handle' arguments are replaced
by opaque types. This allows to encapsulate all the needed
state in the handle, and use unmodified API between baremetal
and virtualized contexts.

This unifies the behaviour between the LAVA, baremetal, and CI-Tron
farms by ensuring every job has access and runs the same scripts.
The init-* scripts are however still sourced from outside the build
artifact, hopefully not for too long.

This should be faster than 32_ABGR.
Also, stencil exports are changed from UINT16_ABGR to 32_GR,
which should have no effect on performance.

Just like other input loads, radeonsi needs to know the barycentric
coordinates for it. This adds the src and determines the optimal barycentric
coordinates in nir_lower_point_smooth, the only producer of the intrinsic.

When using Zink with VK_EXT_descriptor_buffer enabled on IMG proprietary
drivers, the rendering behavior is incorrect and uniforms are not
updated properly (the gears of es2gears_x11 become all red and
overlaps).
Use lazy descriptors for IMG proprietary driver unless explicitly
overriden for testing purpose.

The goal is to reduce symbol pollution, especially when building
with Perfetto support, which previously led to an excessive number
of exported symbols.
objdump -T build/src/egl/libEGL_mesa.so.0.0.0 | grep perfetto | wc -l
- before: 6963
- after: 0
The new egl.sym version script explicitly exports only relevant egl and
MesaGLInteropEGL symbols, while marking all others as local.
While this change effectively removes all Perfetto-related exported symbols,
some C++ standard library symbols remain as undefined. These are pulled in
by the linker due to dependencies.

Initial "compilable" version of mesa/gfxstream on Windows. For now it is
achieved through "#if !DETECT_OS_WINDOWS" directives hence it is NOT
functional. The compilation works with mingw only and the compilation is
tested in a windows host. This commit is intended to only pass the
compilation process without errors.
Also created stub code for a future windows implementation.
