* upgraded the protocol id to version 2 (i.e. /kad/2.0.0) and made it so v2 peers running in server mode respond to queries from v1 peers. Note: v2 peers will only send queries using the v2 protocol, will only add v2 peers to their routing tables, and will only tell v1 peers about v2 peers.
* to run a forked network we now use network specific protocol prefixes instead of manually setting protocol IDs. Use the ProtocolPrefix option instead of the Protocols option.
* emit errors during initialization if the user misuses the default protocol prefix by setting parameters inconsistent with the default protocol's network specification
* since the Client option has been deprecated it's been removed from the dht's options. While deprecated it is still available in the dht options package. Setting `Client(false)` now puts the node into ModeAuto.
* created Mode(ModeOpt) option for choosing between auto/client/server modes
* Auto mode internally switches the DHT between client and server modes based on the EvtLocalReachabilityChanged event emitted on the event bus (e.g. by AutoNAT)
* routing table management of peers that switch between client and server mode while we are connected to them (i.e. are in auto mode)
* removed Client(bool) option, becoming a DHT client is specified using Mode(ModeClient) instead
* feat: consume identify events to evaluate routing table addition
* fix: routing table no longer gets an update just because new messages have arrived or been sent
* fix: add already connected peers into the routing table before listening to events

Related to #453 but not a fix. This will cause us to actually return early when
we start blocking on sending to some peers, but it won't really _unblock_ those
peers. For that, we need to write with a context.
It's currently 10 minutes. This change will kill all inbound DHT streams that
haven't been used in 1 minute.
We keep streams around to avoid the cost of setting up new streams (the
multistream overhead, mostly). However, each one of these takes at least one
goroutine and some other state.
Ideally, this will let us run multiple DHTs side-by-side without keeping one
stream per peer per DHT open.
This was causing us to build up a bunch of background goroutines. Technically,
we should be resetting all these streams when the DHT stops. However, we don't
actually unregister stream handlers from the host so, really, nothing will
actually stop till the host stops. When it does, it'll kill all the streams
anyways.
We usually _explicitly_ call connect before calling `prep` but we may disconnect
somewhere in-between. We _don't_ want to get stuck here dialing if the context
has been canceled.
The protobuf writer performs multiple small writes when writing a
message. We need to buffer these, otherwise we'll send out a packet for
each Write call.
Previously, we'd only retry when a write failed (in case the peer was using
single-use streams). However, in the new world of half-open streams, writes
still succeed on remote-closed streams so this isn't sufficient. Instead, we
need to retry on read failure as well.
Note: this was technically broken before because a peer could write on a stream
before receiving the close message causing the write to succeed but the
subsequent read to fail.

According to golang standards, these should not be capitalized nor having a trailing period, AFAIK.
