    Add support for posix_openpt().
    
    Instead of opening /dev/ptmx directly, we should use the proper
    posix_openpt() function to obtain a pseudo-terminal. Some operating
    systems, such as FreeBSD 8 and later, implement pseudo-terminal master
    device nodes as a special file descriptor type, like sockets. They do
    not support creation of pseudo-terminals through /dev/ptmx.
