An implementation of the SOCKSv4 protocol.
@type logging: L{str} or L{None}
@ivar logging: If not L{None}, the name of the logfile to which connection
information will be written.
@type reactor: object providing L{twisted.internet.interfaces.IReactorTCP}
@ivar reactor: The reactor used to create connections.
@type buf: L{str}
@ivar buf: Part of a SOCKSv4 connection request.
@type otherConn: C{SOCKSv4Incoming}, C{SOCKSv4Outgoing} or L{None}
@ivar otherConn: Until the connection has been established, C{otherConn} is
L{None}. After that, it is the proxy-to-destination protocol instance
along which the client's connection is being forwarded.

The second half of the SOCKS connection setup. For a SOCKSv4 packet this
is after the server address has been extracted from the header. For a
SOCKSv4a packet this is after the host name has been resolved.
@type server: L{str}
@param server: The IP address of the destination, represented as a
dotted quad.
@type user: L{str}
@param user: The username associated with the connection.
@type version: L{int}
@param version: The SOCKS protocol version number.
@type code: L{int}
@param code: The command code. 1 means establish a TCP/IP stream
connection, and 2 means establish a TCP/IP port binding.
@type port: L{int}
@param port: The port number associated with the connection.
