Move system/OpenglCodecCommon into shared/OpenglCodecCommon so it's code can be shared among more components of the project. Move tests/ut_renderer/TimeUtils.* into a the common area Annotate ErrLog.h and GLDecoderContextData.h with the project license statement Change-Id: Ieea42e95edd5ad89fda4cfa40356a012304ee976
