Rayhaan JaufeerallyandClaude Fable 5.1 f9ef781d51 Check roles in OPEN and prevent route leaks with Only to Customer (RFC 9234)
A peer's configured role now does three more things:

- Our OPEN carries the BGP Role capability with what we are to the peer.
  A peer whose own says it is something that does not pair with that, or
  that sends two different roles, is refused with OPEN Message Error /
  Role Mismatch. A peer that says nothing is accepted unless require_role
  is set. A role on a peer in our own AS is a configuration error.
- Routes from a provider, a peer or a route server are marked Only to
  Customer on the way in if they are not already, and our routes are
  marked on the way out to a customer, a peer or a route server client.
- A marked route from a customer or route server client, or from a peer
  with someone else's mark, is a leak and is refused. No policy setting
  turns that off.

The packet crate gains the Only to Customer attribute (malformed:
treat-as-withdraw), and the Role Mismatch subcode is corrected from 8 to
11.

The status page shows whether the peer confirmed its role.
