Log message:
Change the Adj-RIB-Out to a per peer set of RB trees. The way RIB data
structures are linked does not scale for the Adj-RIB-Out and so inserts
and updates into the Adj-RIB-Out did not scale because of some linear
list traversals in hot paths.
A synthetic test with 4000 peers announcing one prefix each showed that
the initial convergence time dropped from around 1 hout to around 6min.
Note: because the Adj-RIB-Out is now per peer the order in which prefixes
are dumped in 'bgpctl show rib out' changed.
Tested and OK job@, benno@, phessler@
