ADR 30: Bolt Handshake Manifest v1

[StephenCathcart]

Implemented the new Bolt Protocol Handshake Manifest v1 negotiation.

The client now sends a handshake proposal with a manifest marker (00 00 01 FF) in addition to the legacy protocol proposals.

When the server selects the manifest negotiation, the client reads a variable-length count of supported protocol versions, the list of offered protocol versions, and a capability bit mask (all encoded as Base128 varints). The client then selects an acceptable protocol version along with capabilities and sent immediately before the HELLO message.
