The additional provision of GL_OES_copy_image is that it work for ETC.
However many desktop GPUs don't have native ETC support, so st/mesa does
the decoding by hand. Instead of discarding the compressed data, keep it
around in CPU memory. Use it when performing image copies.

This enables GL_shader_draw_parameters and GL_ARB_indirect_parameters as well
as a properly accelerated implementation of GL_ARB_multi_draw_indirect.
Enabling the feature requires a sufficiently uptodate firmware -- those have
already been released a long time ago, although this does mean that the
feature only works with the amdgpu kernel module, since the radeon module
doesn't have a way to query the firmware version.
