I don't see the point why we want to use context0 to do transfer.
If we always use original context to do transfer, then we can
avoid sync between contexts for mobile GPU.

Move resource lookup up from vrend to virglrenderer for
vrend_renderer_export_query. Now that the last user of
vrend_renderer_res_lookup is gone, we can remove the helper.
After this change, it becomes clear that vrend deals with
vrend_resource mostly. The only exceptions are the
virgl_context::{attach_resource,detach_resource,transfer_3d}
callbacks.

Add virgl_context::transfer_3d, and when ctx_id is specified, use

When ctx_id is not specified, the resource is a dumb/scanout
resource and is never referenced by submit_cmd. It does not need to
go through the callback. There is no way to either.

We want to move resource lookup up from vrend to virglrenderer for

Add and use virgl_resource_{attach,detach}_iov.
When the iov of a virgl_resource is changed, we should in theory
notify all contexts where the virgl_resource has been attached to.
But because we plan to move to immutable iov for other renderers,
only vrend contexts need to be notified. And because vrend contexts
use vrend_resource and refcount, we only need to update
vrend_resource.

Move resource lookup up from vrend for

These functions are mostly for dumb/scanout resources, and they need
information that virgl_resource does not have. I intentionally pass
pipe_resource down to vrend to emphasize that there is no

It's desirable to query or modify virgl_renderer state for various values.
We've done it for resources (virgl_renderer_get_fd_for_texture /
virgl_renderer_get_fd_for_texture2 / virgl_renderer_resource_get_info) a
few times, but more parameters are often desired.
Let's define a protocol instead. That way, more queries/operations (is "ctx
{num} lost?", "is x host feature supported?") can be formulated.
It's also possible to put the protocol in virgl_hw.h, so in theory
the guest can recieve a response directly from virglrenderer. Any
opinions on this?

Inside the guest, glmark2 typicially runs twice as fast with the thread
sync. Although in general, the performances seems to be about +30%. The
benefits is mostly for CPU-bounds tasks (when main the thread hits 100%)
