New version.

I renamed r600_ functions to si_ in radeonsi to avoid duplicate symbols.
Some duplicate code is now in radeon/r600_{blit,texture}_common.{c,h}.

Tested on AMD Fusion [Radeon HD 6310].
Built with:
../configure --enable-xvmc --enable-vdpau --enable-texture-float --enable-debug
--with-dri-drivers="" --with-gallium-drivers=r600,radeonsi --enable-dri
--enable-glx --enable-osmesa --enable-gles1 --enable-gles2 --enable-openvg
--enable-gbm --enable-xa --enable-gallium-egl --enable-gallium-llvm
--enable-gallium-gbm --enable-r600-llvm-compiler --enable-opencl
