An untyped resource is a virgl_resource without pipe_resource while
vrend_context works with pipe_resources exclusively. When an untyped
resource is attached, we defer the insersion into res_hash until

Capset ids belong to virgl_hw.h. Mesa uses magic numbers right now
and can be fixed with this change.
Capset ids are also leaked in virtio_gpu.h, for use with
virgl_renderer_get_cap_set by qemu. We should replace
virgl_renderer_get_cap_set by something that enumerates all capsets
to stop the leaking, but that is another story.

This change makes a set of changes to increase the range of gbm-based
resources that can be allocated:
- Add VIRGL_BIND_LINEAR to support linear gbm allocations.
- Relax the bind flag argument check if VIRGL_BIND_SHARED or
VIRGL_BIND_LINEAR is set.
- For resources allocated from gbm, only try to create an image if one
of the render target or sampler view bind flags is set.
- Don't try to calculate the internal image format for external images.
This change also fixes a use-after-free that could occur if external
image creation failed.

When we add new feature checks on the host side that is used to enable
a cap conditionally in the guest that was enabled unconditionally before
we might end up with a feature regression when a new mesa version is
used with an old virglrenderer version that doesn't check for that cap.
To work around this problem add a version id to the caps that corresponds
to the features that are actually checked on the host so that it can be
checked in the guest whether this cap was actually checked for or whether
it should be enabled unconditionally.
The id should be incremented whenever a new feature check is added that
might result in a feature regression in the guest when run on an old host.

The enhanced layout extension allows for gaps in the streamout bindings
so we have to be able to handle no-handles in the middle of the target array.
TGSI also has to deal with components outputs where multiple outputs
can be mentioned in the TGSI. It's safe for use to just skip the
extra outputs at least for the tests I've been able to run.
Once we have those changes in place, the renderer can expose the
new CAP bit to the host without any further host extension checks.
