The message handling in this reactor is all under control of the reactor
itself, and does not call out to callbacks or other externally-supplied code.
It doesn't need to check for panics.

- Remove an irrelevant channel ID check.
- Remove an unnecessary panic recovery wrapper.

The PEX reactor has a simple feedback control mechanism to decide how often to
poll peers for peer address updates. The idea is to poll more frequently when
knowledge of the network is less, and decrease frequency as knowledge grows.

This change solves two problems:

1. It is possible in some cases we may poll a peer "too often" and get dropped
   by that peer for spamming.

2. The first successful peer update with any content resets the polling timer
   to a very long time (10m), meaning if we are unlucky in getting an
   incomplete reply while the network is small, we may not try again for a very
   long time. This may contribute to difficulties bootstrapping sync.

The main change here is to only update the interval when new information is
added to the system, and not (as before) whenever a request is sent out to a
peer. The rate computation is essentially the same as before, although the code
has been a bit simplified, and I consolidated some of the error handling so
that we don't have to check in multiple places for the same conditions.

Related changes:

- Improve error diagnostics for too-soon and overflow conditions.
- Clean up state handling in the poll interval computation.
- Pin the minimum interval avert a chance of PEX spamming a peer.

<blockquote>
<h2>v1.4.0</h2>
<h1>Winter 2022 Release ❄️</h1>
<p>Another season, another release!</p>
<h2>Goodbye viper! 🐍 🚀</h2>
<p>The core Cobra library no longer requires Viper and all of its indirect dependencies. This means that Cobra's dependency tree has been drastically thinned! The Viper dependency was included because of the <code>cobra</code> CLI generation tool. <a href="https://github.com/spf13/cobra-cli/releases/tag/v1.3.0">This tool has migrated to <code>spf13/cobra-cli</code></a>.</p>
<p>It's <em>pretty unlikely</em> you were importing and using <strong>the bootstrapping CLI tool</strong> as part of your application (after all, it's just a tool to get going with core <code>cobra</code>).</p>
<p>But if you were, replace occurrences of</p>
<pre><code>&quot;github.com/spf13/cobra/cobra&quot;
</code></pre>
<p>with</p>
<pre><code>&quot;github.com/spf13/cobra-cli&quot;
</code></pre>
<p>And in your <code>go.mod</code>, you'll want to also include this dependency:</p>
<pre><code>github.com/spf13/cobra-cli v1.3.0
</code></pre>
<p>Again, the maintainers <em>do not anticipate</em> this being a breaking change to users of the core <code>cobra</code> library, so minimal work should be required for users to integrate with this new release. Moreover, this means the dependency tree for your application using Cobra should no longer require dependencies that were inherited from Viper. Huzzah! 🥳</p>
