ByteArrayLengthHeaderSerializer headerSize Enhancement

Enhancement

ByteArrayLengthHeaderSerializer maintains headerSize, but it seems an inclusive/exclusive indicator is missing.

Some TCP clients would set the payload size - in the headerSize - inclusive the header size, while other TCP clients would set the payload size exclusive the header size.

ByteArrayLengthHeaderSerializer current implementation assumes exclusive mode, which results with wrong serialization/deserialization if the client uses inclusive mode.

Example:
TCP client sends a stream of 108 bytes, with headerSize = 2. Spring assumes that headerSize value would be 106, while our TCP client (3rd party, we cant control) sends headerSize value set to 108. As a result Spring applies wrong ser/des.
