Subject: [PATCH] Fix missing/wrong includes for BSD

Fix a few missing includes that prevented building on BSD systems.

* Client: the proper way to get MAXHOSTNAMELEN is from <sys/param.h>,
  not from <rpc/types.h>.

* Positioner/Direction: std::hash is declared in <functional>.

* Positioner/OutputNetworkSocket: get struct sockaddr from
  <sys/socket.h>, not from <netinet/in.h>.
