It is always false because venus requires per-context fencing. However,
when it is true (in a private branch), it means
virgl_renderer_create_fence
virgl_renderer_poll
virgl_renderer_export_fence
(but not virgl_renderer_get_poll_fd)
works with venus.

We introduce vkGetVenusExperimentalFeatureData100000MESA to negotiate
experimental venus features under development between the guest and the

experimental features will be cleaned up and merged into core upon

There is no valid reason for the guest to pass bad resource ids.
Because resource creation failures are not propagated back to the guest,
they are the most common reason for the guest to pass bad resource ids.
When that happens, failing earlier makes things easier to debug.

A vrend_context structure contains a current vrend_sub_context, which
in turn keeps references on various resources like textures, VBOs,
index buffers, etc. which are used for actual drawing operations.
Certain actions can change the current sub-context in use.
There is a split of what resources are cleaned up directly as part of
a context destruction and which are handled by the sub-context
destruction. VBOs, while referenced by sub-contexts, are cleaned up by
the context. To do that, it uses the at the time of destruction
current sub-context to access these. As a result, only the VBOs in the
active sub-context are cleaned up; every other sub-context referenced
by the context will keep references to the VBOs used.
The responsibility of VBO dereferencing is moved to the destruction of
the sub-context, so all VBOs, not just the one from the current
sub-context, are dereferenced during the destruction of a context.
Closes#198
