* cygheap.cc (init_cygheap::close_ctty): Avoid closing console-cttys since they
don't use archetypes and this will just result in double frees.
* dll_init.cc (dll_list::protect): Define.
(dll_list::alloc): Guard list access.
(dll_list::detach): Ditto.
* dll_init.h (dll_list::protect): Declare new muto.
(dll_list::guard): Define/declare function to guard list access.
* fhandler_termios.cc (fhandler_termios::sigflush): Avoid SEGV in pathological
condition of get_ttyp() == NULL.
