Allow wtap_read() and wtap_seek_read() to return non-packet records.
This is the first step towards implementing the mechanisms requestd in bug 8590; currently, we don't return any records other than packet records from libwiretap, and just ignore non-packet records in the rest of Wireshark, but this at least gets the ball rolling.
