HttpURLConnection.java, [...]: Reworked import statements.

2003-06-19  Michael Koch  <konqueror@gmx.de>

	* java/net/HttpURLConnection.java,
	java/net/Inet4Address.java,
	java/net/Inet6Address.java,
	java/net/SocketImpl.java,
	java/net/URLClassLoader.java:
	Reworked import statements.
	* java/net/InetAddress.java
	(getByAddress): Simplified.
	* java/net/ServerSocket.java
	(ServerSocket): Moved special handling during bind operation to
	bind().
	(bind): Handle different cases when trying to bind a socket.
	* java/net/URLConnection.java
	(getHeaderFieldDate): Merged with classpath.
	(getHeaderFieldInt): Likewise.
