This CL adds a new flag and associated parsing code for marking
incremental state as "stable". By stable, we mean that for a given piece
of interned data you never define the same incremental scoped id with
a different value anywhere else in the trace.

This property is necessary for us to continue allowing the packet
through the central proto reader code instead of just being dropped. The
existing behavior is unchanged and works the same as it does today.
