Currently the getnetworkinfo returns something like:

"localservices": "0000000000000449",

Manually parsing this consistently gives me a headache (see also sipa/bitcoin-seeder#77).

It would be useful to parse this and show the right combination of NODE_NETWORK, NODE_GETUTXO, NODE_BLOOM, NODE_WITNESS, NODE_NETWORK_LIMITED and NODE_COMPACT_FILTERS. In addition the help text for getnetworkinfo could be expanded to mention the right BIP numbers for known flags.

There is some ad hoc parsing to populate e.g. localrelay, etc (?). Their help text could also refer back to NODE_GETUTXO.
