Prune local tags that don't exist on remote

All "naked" version tags from gx are now prefixed with gx/. The old ones should be removed from local checkouts to avoid repushing. This command removes local tags that don't exist on the remote.

git fetch --prune <remote> '+refs/tags/*:refs/tags/*'

Travis turd template

This template does CI for both gx and go-mod:

The first one is whether a libp2p host will advertise its (pid, multiaddr) mapping in a networks' DHT after constructing the node with a `libp2p.Routing(makeDHT)` option.
Right now this is all we do in the filecoin network and we don't seem to be advertising id,addr records in the dht.
Wondering if we're missing an obvious `provideRouteToMe` call or something like that

anacrolix [2:11 PM]
I’ll have to check, but a typical DHT will routinely reestablish its own presence to nearby peers, and announce itself during bootstraps.
In the context of libp2p, that should include the peer ID and routing information like multiaddrs
