* fhandler_tape.cc: Create mutex with inheritance according to setting
of O_CLOEXEC flag.
* pipe.cc: Replace usage of O_NOINHERIT with O_CLOEXEC.
(fhandler_pipe::init): Simplify setting close_on_exec flag.
(fhandler_pipe::open): Remove setting close_on_exec flag.

flag to follow POSIX semantics.
* security.h (sec_none_cloexec): New define.
* syscalls.cc (dup): Add missing extern "C" qualifier. Accommodate
