        Handle reading of Proxy classes. Never drain(), just write
        TC_ENDBLOCKDATA. Rethrow ObjectStreamExceptions.
        (drain): Check writeDataAsBlocks before calling writeBlockDataHeader.
        (flush): Call flush(), not just drain().
        (writeBoolean): Always use blockDataOutput.
        (writeByte): Likewise.
        (writeShort): Likewise.
        (writeChar): Likewise.
        (writeInt): Likewise.
        (writeLong): Likewise.

        (putfield (put(String,Object))): Throw IllegalArgumentException if
        field cannot be found.
        (putfield (write(ObjectOutput))): Remember old BlockDataMode.
        (writeArraySizeAndElements): Write byte[] in one go.
        (writeFields): Write TC_ENDBLOCKDATA when call_write_method, otherwise
        set BlockDataMode to false.
        (annotateProxyClass): New method.
        (defaultProtocolVersion): Now defaults to PROTOCOL_VERSION_2
        (getField): No longer native.
        (getMethod): Likewise.
        (setBlockDataMode): Always drain() on switch, return old mode.
        (static): New static code block.
        * java/io/natObjectOutputStream.cc: Removed.
        * java/io/ObjectInputStream.java (getField): No longer native.
        (getMethod): Likewise.
        (readObject): Remember and reset old BlockDataMode. Track whether
        object is consumed. Handle TC_ENDBLOCKDATA, TC_PROXYCLASSDESC and
        TC_LONGSTRING.
        (defaultReadObject): Set BlockDataMode to false during readFields.
        (resolveClass): Create new SecurityManager if necessary.
        Use Class.forName() if null ClassLoader found.
        (read(byte[],int,int): Copy remaining bytes to data before calling
        readNextBlock().
        (readFields): Set and reset BlockDataMode on call_read_method.
