Replace iface cache key with netid. Replace _mark with netid. Mark sockets used to test IPv4/IPv6 support as well as sockets used to determine source address for rfc6724 sort. Remove pid/uid mappings (functionality moved to system/netd). Do not create resolv_cache when it does not exist, but rather only when DNS configuration is supplied. Clean up unused functions.
