MFC 243185, 243188, 243212:

Add -fib modifier to specify FIB number. The FIB number can be in a
comma-separated list and/or range specification:

# route add -inet 192.0.2.0/24 198.51.100.1 -fib 1,3-5,6

Although all of the subcommands supports the modifier, "monitor" does not
support the list or range specification at this moment.

Extend route command:
- add show as alias for get
- add weights to allow mpath to do more than equal cost
- add sticky / nostick to disable / re-enable per-connection load balancing

This adds a field to rt_metrics_lite so network bits of world will need to be re-built.
