draw: add support for later transform feedback extensions
This adds support to draw for the new features of transform feedback. a) fix count_from_stream_output, using max_index+1 for now but it looks like it should be valid as its derived from the vertex elements/vbo. b) fix striding and dst offsets in output buffers - was just wrong before. c) fix crash if tfb is suspended (so.num_targets == 0) This also enables the new features on softpipe. It should be possible to enable them on llvmpipe as well after this commit, but would need to schedule piglit runs. Signed-off-by: Dave Airlie <airlied@redhat.com>
