Sometimes you encounter peers with lots of addresses. When this happens
you can attach more than 10x event listeners to the abort signal we
use to abort all the dials - this causes node to print a warning
which is misleading.
This PR increases the default number of listeners on the signal.
Fixes#900
Stop the dht before the connection manager, otherwise in-flight eviction pings fail and we move on to the next one when we should just abort them all.
Also pulls in the fix from #1039 and splits the auto-dialler out from the connection manager as during shutdown it can get into a weird state where it's simultaneously killing and creating connections so stop auto-dialling things before we cause connections to dip below the low watermark by killing existing connections.
Fixes: https://github.com/ipfs/js-ipfs/issues/3923
`interface-datastore` now only contains the interface definition,
`datastore-core` has the various implementations.
BREAKING CHANGE: datastore implementations provided to libp2p must be compliant with interface-datastore@6.0.0
* chore: remove ipfs-utils dep
We only use it for the env detection, so use [wherearewe](https://www.npmjs.com/package/wherearewe)
instead which is that, but pulled out into a tiny module.
The `TextDecoder` class is global everywhere we support so we don't
need to pull it in from `ipfs-utils` and it's been removed from v8
anyway.
* chore: update ipfs-http-client
* fix: give stats initial values
Otherwise the compiler cannot derive the type and thinks `stats.snapshot` returns `{}`
* fix: add type shape to moving averages as well
BREAKING CHANGES:
top level types were updated, multiaddr@9.0.0 is used, dialer and keychain internal property names changed and connectionManager minPeers is not supported anymore
* feat: add uPnP nat manager
Adds a really basic nat manager that attempts to use UPnP to punch
a hole through your router for any IPV4 tcp addresses you have
configured.
Adds any configured addresses to the node's observed addresses list
and adds observed addresses to `libp2p.multiaddrs` so we exchange
them with peers when performing `identify` and people can dial you.
Adds configuration options under `config.nat`
Hole punching is async to not affect start up time.

* fix: store provider multiaddrs during find providers
Changes the behaviour of `libp2p.contentRouting.findProviders` to store
the multiaddrs reported by the routers before yielding results to
the caller, so when they try to dial the provider, the multiaddrs are
already in the peer store's address book.
Also dedupes providers reported by routers but keeps all of the addresses
reported, even for duplicates.
Also, also fixes a performance bug where the previous implementation would
wait for any router to completely finish finding providers before sending
any results to the caller. It'll now yield results as they come in which
makes it much, much faster.
