* java/net/DatagramSocket.java (laddr): Removed. (DatagramSocket): Removed attempts to get or set laddr if null. (getLocalAddress): Reimplemented per spec. * java/net/MulticastSocket.java (setTimeToLive): Throw exception when ttl is 0. (joinGroup): Throw NullPointerException if any argument is null. (leaveGroup): ditto. * java/net/PlainDatagramSocketImpl.java: Updated comments. * java/net/PlainSocketImpl.java (timeout): Added. (getInputStream): Added FIXME comment on how to support timeouts for TCP. * java/net/ServerSocket.java (ServerSocket): Added FIXME comment. * java/net/Socket.java: Added FIXME comments to identify conflicting specs between the JCL and JDK 1.2 documents. * java/net/natPlainDatagramSocketImpl.cc (bind): Use INADDR_ANY if host is null. Get localport value resolved by kernel if bind lport is 0. (receive): Implemented support for timeouts in UDP. (setOption): Implemented based on natPlainSocketImpl version. (getOption): ditto. * java/net/natPlainSocketImpl.cc (bind): Get localport value resolved by kernel if bind lport is 0. (connect): Get localport value resolved by kernel if bind wasn't done to set localport. (accept): Implemented support for timeouts for ServerSocket. (setOption): Save value for SO_TIMEOUT. (getOption): Return timeout for SO_TIMEOUT. From-SVN: r27230
