* dtable.cc (dtable::delete_archetype): Improve debugging output.

Browse Source 
(dtable::init_std_file_from_handle): Close console handle early, before
initialization.  Build up openflags for passing to open_setup, just to be safe.
(last_tty_dev): New variable.
(fh_last_tty_dev): New macro.
(fh_alloc): Try again to keep track of previously opened tty, this time by just
saving the device and using that to potentially open an archetype.  Avoid
setting the "/dev/tty" name if the creation of the fhandler failed.
(build_fh_pc): Remove unused second argument.  Reorganize how and where the
name is set.  Set last_tty_dev as appropriate.  Avoid a NULL dereference in a
debug printf.
* dtable.h (build_fh_pc): Reflect removal of second parameter.
* fhandler.cc (fhandler_base::reset): Use new '<<' operator to copy pc since it
preserves any potentially previously set name.
(fhandler_base::set_name): Ditto.
* fhandler.h (fhandler_*::clone): Throughout use ccalloc to allocate new
fhandler, primarily to make sure that pc field is properly zeroed.
(fhandler_termios::last): Eliminate.
(fhandler_termios): Remove setting of last.
(fhandler_base::~fhandler_termios): Ditto.
* fhandler_console.cc (fhandler_console::open): Don't make decisions about
opening close-on-exec handles here since it makes no sense for archetypes.
(fhandler_console::init): Assume that input handle has already been opened.
* fhandler_termios.cc (fhandler_termios::last): Delete.
* path.h (path_conv::eq_worker): New function.  Move bulk of operator = here.
(operator <<): New function.
(operator =): Use eq_worker to perform old functionality.
