Support BLOB resources creation, mapping and unmapping by calling the
new stable virglrenderer 0.10 interface. Only enabled when available and
via the blob config. E.g. -device virtio-vga-gl,blob=true
I have another concern about delaying virgl_renderer_resource_unref()
until the resource gets unmapped; the guest will expect the resource ID
will be available for a new resource immediately after
VIRTIO_GPU_CMD_RESOURCE_UNREF, but it will break the assumption and may
corrupt things.
