Subject: [PATCH]  For compatibility with opencv3.x issue#276

mentioned in https://github.com/yjxiong/temporal-segment-networks/issues/276
This is a contradiction: The build_all.sh install opencv 2.4.13.6, opencv 2.4.13.6 don't have opencv_contrib, so it surely will not have xfeatures2d. But dense_flow/src/dense_warp_flow_gpu.cpp needs xfeatures2d for compiling, so actually i have to modify the build_all.sh to install opencv3.x, not 2.x and changed the api format from 2.x to 3.x in dense_flow.cpp, accordingly
