95c08e082c bgpd: fix resolvedPrefix in show nexthop json output
While populating  the nexthop info for "show bgp nexthop json", resolvedPrefix
is added in parent json object instead of json_nexthop object.
This results in displaying wrong resolvedPrefix for nexthops.
Fixing the same by adding resolvedPrefix to json_nexthop object, so that
the proper resolvedPrefix would be displayed for the respective nexthop

68358c0f92 bgpd: Fix for match source-protocol in route-map for redistribute cmd
A redistribute cmd can have a route-map attached to it and adding the
match source-protocol to that route-map means BGP to filter which
protocol routes to accept among the bunch of routes zebra is sending.

Fixing this since this wasnt implemented earlier.

ea4823964c bgpd: In bgp_withdraw attempt to avoid a if statement on every pass
We have this:

if ( (safi == SAFI_UNICAST) && ...)
    do stuff
if ( (safi == SAFI_MPLS_VPN) && ... )
    do stuff

this leads to having to test safi multiple times if safi is
SAFI_UNICAST.  Let's make it a else if as that we know that
the safi is going to not change.

Reset is due to the source address change.

With this patch, we reset the session only if it's a _REAL_ BFD down event, which
means we trigger session reset if BFD session is established earlier than BGP.

the only explanation is that the conversion from struct timeval
