client to enable drawable shadowing. Allocate linear GBM buffers to make
them shareable between different devices.

We can now use gbm_bo_map(..) directly to match Mesa.
If minigbm doesn't define the needed use flags, we define it
internally.
This should allow us to build with minigbm allocation enabled and
use the Mesa gbm header.

Like in vrend_renderer_transfer_internal, virgl_gbm_transfer is a
special path that is generally preferred. However, a copy transfer
can be a synchronized transfer. We don't want to use GBM in that
case.

Gbm-resources can be used for data blobs. These are created with a
height of 1 and the required width, which can easily exceed the maximum
supported texture width.

Mesa emulates planar format sampling with per-plane samplers. With this
change, the guest can pass the plane index when creating a sampler view
from a virgl resource to create a per-plane sampler view. The index can
be passed in place of the texture layer, as that will always be 0 for
planar images.

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].

Turns out some files managed to have a mix between 2, 3, 4 and tabs for

that fixes all of them.

The idea is to have a unix socket and possible shmem protocol
between a renderering server and local gallium sw driver.
This could be used to validate virgl without qemu with piglit.
