Teletype

Elixir TTY/PTY native nif/ports.

See terminal for a modern reactish API.

Future

• NIF ptc
• TTY reset
• PTC resize

Issues

• ttyname(0) works from a nif
• ttyname(0) fails from a port (NULL)
• ports fail to acquire a controlling tty
• ports fail to receive SIGWINCH signals
• ports fail to become session leaders (setsid)
