* java/net/InetAddress.java
	(zeros): Removed.
	(ANY_IF): Initalizie in static block.
	(static): Load library with native methods here and initialize ANY_IF.
	(isAnyLocalAddress): Check if equal to ANY_IF.
	(equals): Use addr directly instead of addr1. Simplify for loop.
	(toString): Rename "result" to "host" and add IP address allways.
	(getLocalHost): Merged documentation from classpath.
	* java/net/ServerSocket.java
	(ServerSocket): New package-private constructor used by java.nio.
	* java/net/URLConnection.java
	(getRequestProperties): Check if already connected.
