Improve the resiliency of the packet deserialization code.
Packet deserializers now check for malformed input while reading the byte
stream. Deserializers are re-implemented as functions that take a byte array
and return a packet object. The old IPacket.deserialize(...) methods have been
deprecated with the goal of eventually moving to immutable packet objects.
Unit tests have been implemented for all Deserializer functions.
