throwing an exception, if the bytes to be compared aren't available in
the tvbuff, we don't need to check for their existence before calling
those routines.

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.

WTAP_ENCAP_ISDN encapsulation type, which includes a pseudo-header
giving the direction (user-to-network or network-to-user) and the
channel number.
Add a new circuit type, using the ISDN channel number as the circuit ID.
Add an ISDN dissector to put the direction and channel number into the
protocol tree and to call the appropriate dissector for the payload
based on the channel (LAPD for the D channel; V.120, PPP, or data for B
channels, based on some heuristics).
