- PathAttribute::UnknownPathAttribute and Capability::UnknownCapability
are PathAttribute::Unknown and Capability::Unknown: the enum already
says what kind of thing is unknown.
- The capability entry types are all named XxxEntry now
(ExtendedNextHopEntry, LongLivedGracefulRestartEntry), rather than two
of them sharing a name with the variant that holds a list of them; and
MultiLabelCompat is MultiLabel, since nothing explained the "Compat".
- Two different things were both called Reflection: what a session needs
to reflect routes (export.rs, still Reflection) and the identifiers a
reflected route must not carry back to us (policy.rs, now
ReflectorIds).
- well_known_allow's peer_is_internal is ibgp, as everywhere else.
