socket: make stream_buf_* functions static

stream_buf_init(), stream_buf_close() and stream_buf_added()
are only used within socket.c, therefore there is noneed to
have them declared in socket.h.

Make them static and remove useless declarations.
This change reuired adding function prototypes in socket.c to
avoid useless code re-ordering.
