service: Write a trusted PacketSequenceID with each packet. A PacketSequenceID identifies each <Producer, Writer> pair uniquely within the scope of a tracing session, i.e. each <producer_id, writer_id> pair is mapped to a PacketSequenceID. It thus identifies all packets that were emitted by the same writer. This is a prerequisite for our new trace event data interning feature, where interning indexes will be scoped to each packet sequence.
