Gallium sends the shaders in the order FS-[GS]-[TES]-[TCS]-VS. If an old
shader program is still bound when a new shader is send, then it would use the
old bounds shader of the previous stage to evaluate the shader key and code
creation might create an invalid shader. Hence, if the shader to be translated
is not yet bound ignore the previous stage when evaluating the shader key
(Gurchtan)

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?

virgl_renderer_transfer_write_iov doesn't work for YUV buffers, since
it's based on glTexSubImage.
We assume the YUV image is not disjoint, since that's currently what
Mesa gbm supports.
For RGBA buffers, this will also eliminate a copy in the cases
where the gbm_bo_map(..) implementation doesn't use a shadow buffer
[i915, mediatek, rockchip].

vrend_clear executes the Gallium clear command which is only called
when the whole viewport is cleared. So far mesa was doing excessive checks
on the scissors, thereby updating the scissors to framebuffer size when they
were disabled, and the according state changes were transmitted to the host.
With mesa/2037478 this was optimized away, so that not disabling the scissors
in the clear command manifested itself as a regression in a number of tests.
Keeping track of the scissor state in the hardware and disabling the scissors
before the clear is executes, and re-enabling them according to the last state
fixes this.
