space_server: bird: prepare large communities
This patch prepares us for adopting Large BGP Communities (RFC 8092). Basic format of Large BGP Communities: <uint32_t asn>:<uint32_t function>:<uint32_t value> We use function 1 for storing prefix type (or relation). We then assign a value to transit, peering, customer and originated prefixes. Large BGP Communities http://largebgpcommunities.net/ https://tools.ietf.org/html/rfc8092 https://tools.ietf.org/html/rfc8195 Esmil: consistent brace placement
