This further enhances xdi_diff_outf() interface so that it takes two common parameters: the callback function that processes one line at a time, and a pointer to its application specific callback data structure. xdi_diff_outf() creates its own "xdiff_emit_state" structure and stashes these two away inside it, which is used by the lowest level output function in the xdiff_outf() callchain, consume_one(), to call back to the application layer. With this restructuring, we lift the requirement that the caller supplied callback data structure embeds xdiff_emit_state structure as its first member.
