xdiff: add a bdiff hunk mode

xdiff generated hunks for the differences (ex. questionmarks in the
`@@ -?,?  +?,? @@` part from `diff --git` output). However, bdiff generates
matched hunks instead.

This patch adds a `XDL_EMIT_BDIFFHUNK` flag used by the output function
`xdl_call_hunk_func`.  Once set, xdiff will generate bdiff-like hunks
instead. That makes it easier to use xdiff as a drop-in replacement of bdiff.

Note that since `bdiff('', '')` returns `[(0, 0, 0, 0)]`, the shortcut path
`if (xscr)` is removed. I have checked functions called with `xscr` argument
(`xdl_mark_ignorable`, `xdl_call_hunk_func`, `xdl_emit_diff`,
`xdl_free_script`) work just fine with `xscr = NULL`.

Test Plan:
Will be tested in a later patch.
