This patch enables mrtWriter to directly access config.MrtConfig values
in case that some new options will be introduced.

This patch introduce "add-paths" structure per AFI-SAFI in order to
enable to store add-paths feature config/state per AFI-SAFI.
Also, this patch renames a few variables to avoid the name collisions.

This patch enables GoBGP to keep the session established
even if the received BGPUpdate message contains some errors,
and to handle these errors according to what defined in RFC7606.
This feature is enabled when 'treat-as-withdraw' in
'neighbors.error-handling.config' is specified to true
in the GoBGP config file.

To reduce the translations of "AfiSafiName" into "bgp.RouteFamily", this
patch introduces "Family" field into "AfiSafiState" and stores the
translated value.

A new socket was created so we must close it before this function
returns _either_ on failure or success. On success, net.FileConn() in
newTCPConn() increases the refcount of the socket so this fi.Close()
doesn't destroy the socket; the caller can use it (and needs to close
it later).

With Destination struct, multiple Paths can be moved from the table
package to the server package in a cleaner way; for features such as
add-path.

currently, route server peers and non route server peers use the
single global rib. To support deterministic-med for non route server
peers, this splits the rib into two; easier to handle the best path
selection in different ways.

If State.NeighborAddress is not set, setting default configs
for the dynamic peers will fail. This patch set State.NeighborAddress
before setting default configs.
And this patch avoids overwriting State.NeighborAddress if it is set.

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 send BMP statistics reports for the following types;
- Stat Type = 11: (32-bit Counter) Number of updates subjected to
treat-as-withdraw treatment.
- Stat Type = 12: (32-bit Counter) Number of prefixes subjected to
treat-as-withdraw treatment.
Note: Currently, this implementation considers only updates or prefixes
received from neighbors, but not enough to follow the handling process
described in RFC7606.

This test case checks whether BGP session is freed or not when Graceful
Restart timer expired.
If BGP session is not freed as expectedly, this test case will exit with
state 1 after waiting 120 seconds and will output the following.
FATA[0147] failed to free the fsm.h.t for 127.0.0.1 BGP_FSM_OPENSENT

This patch enables to create peer-groups,
also supports dynamic configuration to peer-groups.

This patch enables to watch events for monitoring received BGP messages
before the state comparison.
Note: Currently, this event nortifies UPDATE message only, because the
other messages will be handled in FSMHandler and not received at
BgpServer, so BgpServer cannot send event for these messages.

Currently, the TLV fields are implemented as BMPTLV on the Initiation
messages, but not enough decoded and required to be constructed in
binary format.
This patch introduces BMPInfoTLV and makes easy to handle the TLV
fields.
Note: This patch obsoletes BMPTLV structure.

"draft-evens-grow-bmp-local-rib" says the peer header for Loc-RIB
monitoring should include the following values;
- Peer Address: Zero-filled as remote peer address is not applicable.
- Peer AS: Set to the BGP instance global or default ASN value.
- Peer BGP ID: Set to the BGP instance global or RD (e.g. VRF) specific
router-id.
This patch fixes the peer header construction to follow this
specification.
