3d23e41dcb Nest: Use rtable for neighbor lookup
Implicitly define rtables 'local4' and 'local6' and a pair of direct
protocols to fill them. Use modified net_route() for neighbor
lookup to avoid iterating over all interfaces.

7d1c2ea5c0 Nest: Use bitmask of pxlens to speed-up net_route()
Use bitmask to keep track of pxlens that might be in rtable to avoid
unnecessary lookups during net_route().

5c73cd94a5 Nest: Add hash table for interfaces, keyed by index
Useful if one have too many interfaces, as there are per-route
iface index lookups in routing table scan.

e092341df3 Nest: Handle unresolvable routes as invalid
Handle unresolvable routes (recursive routes that cannot be resolved) as
invalid, i.e. deprioritize tham and do not allow them for propagation.
Such route now shows as 'unresolvable' instead of 'unreachable'.

9b73157ea1 BGP: Handle case where capabilites are not used
If peer does not announce capabilities at all, or when we have
capabilities disabled, handle that as implicit IPv4 unicast.

37dbd3fc7a Static: Allow to set multiple static route with different metric
Change the usage of preference to distinguish multiple static routes to a
separate metric attribute, Reuse igp_metric attribute for that purpose.

The static route metric is specified with 'metric' keyword immediately
after the network (to signify it is a part of key):

  route 10.10.0.0/24 metric 10 via 192.168.1.2;

ed97d77073 OSPF: Reset LSAs during area type change
When area is reconfigured to a different type, we need to flush LSAs as
they may not be valid (e.g. NSSA-LSA for non-NSSA area). Also, when we
have have just one OSPF area and that changes type, we could restart OSPF
as there is no state to keep anyway. That solves issue with different
handling of external routes exported to OSPF based of main area type.

cb8ea2d907 OSPF: Basic support for DN-bit handling (RFC 4576)

marked by DN flag and they are ignored by other OSPF routers with VPN-PE
enabled.

a30b9d2800 OSPF: Opaque LSAs and Router Information LSA
Add support for OSPFv2 Opaque LSAs (RFC 5250) and for Router Information
LSA (RFC 7770). The second part is here mainly for testing opaque LSAs.

45426652a2 OSPF: Fix wrong LSA collisions detection
In some circumstances (old LSA flushed but not acknowledged and not
removed) origination of a new LSA may wrongly triggers LSA collision
code. The patch fixes that.

Thanks to Asbjorn Mikkelsen for the bugreport and @mdelagueronniere
for the original patch.

210dbc16c2 BGP: implement Adj-RIB-In
The patch implements optional internal import table to a channel and
hooks it to BGP so it can be used as Adj-RIB-In. When enabled, all
received (pre-filtered) routes are stored there and import filters can
be re-evaluated without explicit route refresh. An import table can be
examined using e.g. 'show route import table bgp1.ipv4'.

bf402c61e6 OSPF: DD seqnum should be initialized only for first attempts
