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.

Use new copyto() fhandler method to copy from/to found archetype. * fhandler.h: Throughout, delete size(), add copyout, clone, and fhandler_* (void *) methods.

(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.
