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.
