util_sync_provider provides a wrapper to manipulate syncobjs.
This allows replacing direct ioctl usages with other functions,
and is going to be used to support vpipe.

This returns the underlying device pointer but as an opaque
uintptr_t.
This will be required because libdrm_amdgpu will return the
same device when called multiple times from the same process.
radeonsi relies on the pointer value to identify if the device
are the same and adjust the synchronisation logic based on that.

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 patch:
- adds a new subquery (AMDGPU_INFO_UQ_FW_AREAS) in AMDGPU_INFO_IOCTL
to get the size and alignment of shadow and csa objects from the
kernel. This information is required for a userqueue consumer (like
MESA/libdrm) to create the userqueue metadata objects properly.
- also adds supporting metadata structures and a high level wrapper
function (amdgpu_query_uq_metadata_info) to the query, to make it
easy to use.
The corresponding kernel changes for this UAPI extension can be found
in amd-gfx mailing list, link:
https://patchwork.freedesktop.org/patch/621390/?series=139715&rev=2
This patch adds support only for the GFX IP, and the other engines may
be supported in subsequent development.

This imports 35 libdrm_amdgpu functions into Mesa.
The following 15 functions are still in use:
amdgpu_bo_alloc
amdgpu_bo_cpu_map
amdgpu_bo_cpu_unmap
amdgpu_bo_export
amdgpu_bo_free
amdgpu_bo_import
amdgpu_create_bo_from_user_mem
amdgpu_device_deinitialize
amdgpu_device_get_fd
amdgpu_device_initialize
amdgpu_get_marketing_name
amdgpu_query_sw_info
amdgpu_va_get_start_addr
amdgpu_va_range_alloc
amdgpu_va_range_free
We can't import them because they make sure that we only use 1 VMID
per process shared by all APIs. (except the marketing name)
