InputStreamReader.java (<init>): Set super.in correctly.

Browse source 
�
	* java/io/InputStreamReader.java (<init>):  Set super.in correctly.
	* java/io/OutputStreamWriter.java (<init>):  Set super.in correctly.
	(writeChars):  Don't be quite so eager to flush.
	* java/io/PrintStream.java:  Rewrite.  Now more similar to
	OutputStreamWriter, using explicit UnicodeToBytes converter.
	Also, autoflush does not need to flush so often.
	* java/lang/natString.cc (getBytes):  More efficient algorithm.
 	(init(jbyteArray,jint,jint,jstring)):  More efficient.
