fib: Source Address Selection
Type: feature
Use the FIB to provide SAS (in so far as it is today)
- Use the glean adjacency as the record of the connected prefixes
= there's a glean per-{interface, protocol, connected-prefix}
- Keep the glean up to date with whatever the recieve host prefix is
(since it can change)
