(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_pty_slave::ioctl): Reflect name/arg change for ioctl_termios. (fhandler_pty_slave::fhandler_pty_slave): Take a "unit" argument. Call setup() here so that we will know the unit number of this fhandler as soon as possible. Set the unit as appropriate. (handler_pty_master::open): Move most stuff to constructor and open_setup. (handler_pty_slave::open_setup): Reflect argument change in pinfo::set_ctty. (handler_pty_master::open_setup): Define new function.

(fhandler_pty_master::~fhandler_pty_master): Define new method. (fhandler_pty_master::ioctl): Reflect name/arg change for ioctl_termios. (fhandler_pty_master::setup): Allocate tty here. Rely on handles being returned from allocated test rather than opening them here. Avoid setting _need_nl here since it is already zeroed in the constructor. Set up device information with DEV_TTYM_MAJOR. * path.h (path_conv &operator =): Take a const argument. (path_conv::dup): Ditto. (pathconv_arg::PC_OPEN): New enum. (pathconv_arg::PC_CTTY): Ditto.
