Move dftest.c back to the top-level directory; that way, all of the

stuff in ui/cli can be stuffed into a libcliui library to link with
TShark, and all of the source files containing main() (except for
Wireshark) are in the top-level directory (dftest isn't any more special
than TShark or capinfos or mergecap or editcap or...).
