* string.c (rb_str_lstrip_bang): new method.

* string.c (rb_str_rstrip_bang): new method.

* string.c (rb_str_associate): should consider STR_ASSOC too.

* eval.c (rb_undefined): do not recurse if method_missing is
  undefined.

* process.c (proc_waitpid): now all arguments are optional.

* process.c (Init_process): waitpid is now alias to wait.

* process.c (Init_process): waitpid2 is now alias to wait2.

* process.c (rb_waitpid): made public.

* ext/pty/pty.c (pty_getpty): avoid disturbing SIGCHLD using
  thread and rb_waitpid.

* process.c (proc_getpgrp): now takes no argument on all
  platforms.

* process.c (proc_setpgrp): ditto.

* ext/socket/socket.c (sock_s_pack_sockaddr_in): added
  Socket::pack_sockaddr_in(). [new]

* ext/socket/socket.c (sock_s_pack_sockaddr_un): added
  Socket::pack_sockaddr_un(). [new]

* ext/socket/socket.c (sock_s_pack_sockaddr_in): added
  Socket::unpack_sockaddr_in(). [new]

* ext/socket/socket.c (sock_s_pack_sockaddr_un): added
  Socket::unpack_sockaddr_un(). [new]
