[ 08:38:38 ed ] socks5net SOCKS v5 application layer gateway and clients
Make net/socks5 compile again after the removal of sgtty.
The net/socks5 port includes <ttychars.h>, even though it is not needed.
This header file got removed with the sgtty interface. Also make the
port prefer <termios.h> over <sys/termios.h>
