    Move SVC code from vp9_spatial_scalable_encoder to libvpx module accessible from ffmpeg

commit 54e88b78b160becc9569fc3c6cb6b0a8c95dc357
Author: Ivan Maltz <ivanmaltz@google.com>
Date:   Tue Oct 8 09:08:40 2013 -0700

    common svc encoding code for sample app and ffmpeg

    added svc_encodeframe.c, svc_context.h, svc_test.cc

    vp9_spatial_scalable_encoder uses vpx_svc_encode
