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.

This patch enables to decode/encode MRT format with BGP routing
information including the geographical location which described in
RFC6397.

RFC5549 allows IPv6 Next Hop address for the advertisement of IPv4
related NLRIs for <AFI/SAFI> of <1/1>, <1/2>, <1/4> and <1/128>.
Currently, the advertisement using the MP_REACH_NLRI is supported,
but IPv4 routes with IPv6 Next Hop is not enough.
This patch enable to advertise IPv4 routes for <AFI/SAFI> of <1/1>
through GoBGP CLI command.
e.g.)
$ gobgp global rib add -a ipv4 10.2.1.0/24 nexthop 2001:2::1

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

RFC4271 9.1.2 Phase 2: Route Selection
If the AS_PATH attribute of a BGP route contains an AS loop, the BGP
route should be excluded from the Phase 2 decision function. AS loop
detection is done by scanning the full AS path (as specified in the
AS_PATH attribute), and checking that the autonomous system number of
the local system does not appear in the AS path. Operations of a BGP
speaker that is configured to accept routes with its own autonomous
system number in the AS path are outside the scope of this document.
Also this commit adds support for allow-own-as option to relax this.

This patch proposes a new way to configure BGP flowspec TCP flags
rules It allows to comply with RFC 5575 by defining flags like this
=SA =A / '!SA' / '=SA&=!U' = means match, ! means not, & means and,
all TCP flags are identified by their first charater S for SYN A for
Ack ...
This patch adds "--reason" option support into the disable neighbor command
which can specify "Administrative Shutdown Communication" on the BGP Cease
NOTIFICATION message.
Usage:
$ gobgp neighbor <neighbor address> disable --reason "some messages"

AdjRibOut isn't in memory so needs to be calculated on the fly.
Doing such for multiple neighbors consumes too much CPU (especially
there are lots of routes).

Since `shutdown` command just sends ADMINISTRATIVE_SHUTDOWN notification
and doesn't change admin-state, neighbors can be get established after
idle-holdtime which is not intuitive from the name of the API.
We can use `reset` command to hard-reset BGP session, and `disable` command
to shutdown(disable) BGP session.

Also don't allocate label for local routes. The label management needs
to work with other components rather than bgp.
