InflaterInputStream (read): Don't return -1 unless the infate() call didn't deliver any output.

	* java/util/zip/InflaterInputStream (read): Don't return -1 unless
	the infate() call didn't deliver any output. Throw a ZipException if
	the needsDictionary() call returns true.
	* java/io/ByteArrayInputStream (read): Remove redundant bounds checks.
	* java/io/InputStreamReader: Use the default buffer size for the
	contained BufferedInputStream.
