Allow more than one circuit with the same circuit ID; a circuit has a
starting and ending frame number, and circuits with the same circuit ID
are sorted by the starting frame number (the last circuit can have 0 as
the ending frame number, meaning "unknown"), and, when looking up a
circuit, we take a frame number as an argument and return the circuit
that includes that frame.
Add a new circuit ID type for X.25 virtual circuits, and use the circuit
mechanism to keep track of the dissector for an X.25 virtual circuit
rather than having a private mechanism.
