* fhandler.h (fhandler_base): Remove obsolete _rpos and _rsize elements.
* fhandler.cc (fhandler_base::open): Ditto.
* fhandler.cc (fhandler_base::fhandler_base): Ditto.
(fhandler_base::read): Ditto. Add more debugging output. Don't issue a \r
when \r\n detected.
* pipe.cc (make_pipe): Streamline slightly. Make debug output more
interesting.
* strace.cc (strace::vsprintf): Use __progname where appropriate to distinguish
strace output when exec'ing.
