this is the first step in unifying surfacetexture and surface. for this reason the header files were not moved, as most of them will eventually go away. NOTE: currently we keep libsurfaceflinger_client.so as an empty library to workaround prebuilt binaries wrongly linking against it. Change-Id: I130f0de2428e8579033dc41394d093f4e1431a00
