This patch updates go-libp2p for the stream interface changes in go-libp2p-core
0.7.0. This is a _significant_ breaking change to streams and all users should
read https://github.com/libp2p/go-libp2p-core/releases/tag/v0.7.0. In practice,
this change should remove a significant footgun.
TL;DR:
* `Stream.Close` now behaves like `net.TCPConn.Close`.
* There is a new `Stream.CloseWrite` (send an EOF) and `Stream.CloseRead` (close
for reading), behaving like their counterparts in `net.TCPConn`.
This is a backwards incompatible change and will require a major version bump
plus an announcement. Users can choose to re-enable SECIO by passing
`libp2p.Security(secio.ID, secio.New)` to the constructor.
1. Fix tests on go 1.15 by avoiding `string(i)`.
2. Fix the autorelay test by making relays announce fake "public" addresses. I'm
not sure how this worked before.
Previously, we'd construct addresses like `/ip4/.../udp/...` instead of
`/ip4/.../udp/.../quic` because we'd use mapped addr (ip + transport + port)
instead of the full external address (ip + transport + port + other
transports...).
* fix: use all interface addresses when we can't find the default route
* fix: don't add advertise unspecified addresses
* fix: resolve addresses before looking up observed addresses
* fix: only advertise global unicast
* fix: filter link-local addresses from advertisement
* test: fix basic host addr tests
Before, we would:
1. Receive a "listen close" event from an event handler, after the teardown started.
2. Try to add a child process to handle the event. This would block because we
were in the teardown.
3. In the teardown, try to unregister the event handler and deadlock
I've now:
* Removed the teardown.
* Switched to a single event loop.
Ideally, we'd remove goprocess entirely. But we'd need to refactor natmgr.

We switched `listenAddrs` from the _interface_ addresses to the raw addresses we
were listening on. Unfortunately, we needed the resolved addresses later in the
function when resolving port mappings.
* Updates yamux to reduce lock contention.
* Updates the peerstore to remove an issue where we'd forget our peer's addresses instead of extending the TTL.
Alternative to #963. Instead of using atomics, this patch ensures that all state
changes are performed on the main thread. It also:
* Threads the context through explicitly to make sure fields changed by the main
thread are never read by the handler goroutines. This isn't strictly necessary
but it makes it easier to reason about.
* Uses a callback to signal "on done". There may be cleaner ways to do this (I
hate callbacks), but this nicely decouples the peer handler from the main loop.
