teor 3260dbff03
Update to NU5 mainnet network protocol version (#9) 
This change should allow the seeder to connect to the network until early 2022.

The `version`, `verack`, `getaddrs`, and `addrs` messages haven't changed,
so the seeder is trivially compatible with future network upgrades.

George Tankersley 16d803bb86 zcash: fix retry logic 
Previously, when a request timed out, that peer would not be removed
from the pending handshake signal map. Since the peer was still in the
map, any attempt to reconnect would fail since it would look like we
were already waiting on a response.

# Zcash DNS seeder
This is a CoreDNS plugin that scrapes addresses of peers from a Zcash network. It's intended as a safer, more configurable, and more scalable replacement for the [zcash-seeder](https://github.com/zcash/zcash-seeder) project.
This is a CoreDNS plugin that scrapes addresses of peers from a Zcash network
and returns them on A or AAAA queries. It's intended as a safer, more configurable, and more scalable
replacement for the [zcash-seeder](https://github.com/zcash/zcash-seeder) project.
It's written in Go and uses [btcsuite](https://github.com/btcsuite) for low-level networking.
It works by connecting to a list of bootstrap peers and requesting new peers by sending `getaddr`
messages. The process is then periodically repeated with the current list of known peers.
This plugin accepts both `addr` and `addrv2` messages, though it ignores addresses that are not
IPv4 nor IPv6. It does not answer `getaddr` requests from other peers.
## Build instructions
This code cannot be used independently of CoreDNS. See [coredns-zcash](https://github.com/ZcashFoundation/coredns-zcash) for instructions.
