RFR: 8297632: InputStream.transferTo() method should specify what the return value should be when the number of bytes transfered is larger than Long.MAX_VALUE

[Brian Burkhalter]

`java.io.InputStream::transferTo` could conceivably return a negative value if the count of bytes transferred overflows a `long`. Modify the method to limit the number of bytes transferred to `Long.MAX_VALUE` per invocation.
