the fun.
* dtable.cc (dtable::stdio_init): Remove special-case call to set_console_ctty
().
* exceptions.cc (sigpacket::process): Conditionally flush terminal input on

(fhandler_termios::get_ttyp): Move here.
(fhandler_termios::sigflush): Declare.
(fhandler_tty_common::get_ttyp): Delete.
* fhandler_console.cc (fhandler_console::get_tty_stuff): Pass this as "arch"
argument.
(set_console_ctty): Delete.
(tty_list::get_tty): Just return pointer to shared console region, delaying
get_tty_stuff until open().
(fhandler_console::init): Treat NULL handle as signifying that console should
be opened with O_NOCTTY flag.  Rename handle argument to the more common 'h'.
* fhandler_termios.cc (fhandler_termios::sigflush): Define.
* fhandler_tty.cc (handler_tty_master::init_console): Pass NULL as first
argument to fhandler_console::init.
* pinfo.cc (_pinfo::set_ctty): Change third parameter to fhandler_termios *.
Add extra debugging.
