* gnu/java/net/protocol/http/Connection.java
	(outputStream): New field.
	(bufferedOutputStream): New field.
	(connect): Initialize outputStream and bufferedOutputStream.
	(sendRequest): Create PrintWriter object from outputStream,
	support HTTP 1.1, send missing HTTP headers and buffered output data
	for POST method.
	(getOutputStream): Set request method to POST if output stream is
	used, return bufferedOutputStream.
	(setRequestMethod): Allow HEAD and POST methods.
	This fixes libgcj PR/6302 and libgcj PR/7752.
