By introducing dynamic neighbor feature,
GoBGP can have dynamic neighbors,
and corresponding Config.NeighboAddress can be empty.
This patch sets State.NeighborAddress for all neighbors,
and gets the neighbor's address from them.

we use the term replace-peer-as instead of as-override
since openconfig is using it.
cli
```
$ gobgp n add <neighbor-addr> as <asn> replace-peer-as
```
config
```
neighbor:
config:
peer-as: <asn>
neighbor-address: <neighbor-addr>
as-path-options:
config:
replace-peer-as: true

At importing a path from an external peer, LOCAL_PREF can be set by an
import policy but at exporting a best path to an internal peer, this
learned, calculated LOCAL_PREF is never used and every time overwritten
by a default value 100.
According to RFC 4271 "5.1.5. LOCAL_PREF" and "9.1.1. Phase 1:
Calculation of Degree of Preference", the learned value should be
advertised to other internal peers.
This fixes it by just removing resetting a non-local path's LOCAL_PREF
by the default value.
when a path has IPv4 NLRI and IPv6 nexthop, handle it in MPBGP manner.
(use mp-reach-nlri path attribute instead of nexthop path attibute)

config.Neighbor.Transport.State.LocalAddress may have zone info and
not be valid ip address format.
Use PeerInfo.LocalAddress instead.

config.TransportState.LocalAddress may have zone info with ipv6 address
like "fe80::x%eth0".
In this case, net.ParseIP() returns <nil>, which leads to set <nil> to
PeerInfo.LocalAddress.

For BGP Nexthop Tracking, this patch enables table package to evaluate
the best path based on the nexthop reachability which validated by IGB.

when rpki validation condition is not configured ( c == "" ), don't

this bug was breaking all policy mechanism when rpki server is configured.

policy can have multiple statements. In each statement, when condition
is matched, route-action is finally evaluated after actions with mods.
When route-action is 'none', we contine to next statement if it exists.
When route-action is 'accept' or 'reject', we stop proceeding.
This patch fixes a bug that route-action can't be set to 'none' which
means route-action always be set to 'accept' or 'reject' and can't proceed
to the next statement.
