Prior to this commit, the how-to documentation would say that Spring
Boot does not support the h2c protocol. While it's not supported
out-of-the-box with a configuration property, this protocol can still be
configured using server customizers.
This commit documents, with code snippets, the server customizers one
should use to configure the h2c protocol in an application - for each
supported server.

Prior to this commit, tests using the `@WebMvcTest` annotation would not
include the `HttpEncodingAutoConfiguration`. This means that, even if
configured, the encoding filter would not be configured in MVC tests,
resulting in an inconsistency with `@SpringBootTest` tests.
This commit ensures that the `HttpEncodingAutoConfiguration` is included
when `@WebMvcTest` is used.

Previously, the shutdown hook was only registered once refresh has
completed. If the JVM was shut down during refresh (or after refresh
and before the hook was registered) the hook wouldn't run and the
partially refreshed context would not be cleaned up.
This commit moves the registration of the shutdown hook to before
refresh processing begins. This ensures that the hook is available
to clean up the context if the JVM is shutdown while refresh is in
progress.

Previously, JettyEmbeddedErrorHandler would change the method of every
request that is handles to GET. This was being done to work around
Jetty's error handling only dealing with GET, POST, and HEAD requests
by default. It had the unwanted side-effect of causing an error
response to a HEAD request having a body as, from the error handling's
perspective, it was a GET request.
This commit updates JettyEmbeddedErrorHandler to only set the method
on a request for which error handling is being performed if the method
isn't already one that will be handled, leaving the method of GET,
POST, and HEAD requests unchanged.
Unfortunately, short of implementing an HTTP client, this change cannot
be tested as the Apache HttpClient, OkHttp, and the JDK's
HttpURLConnection all silently drop the body of a response to a HEAD
request, preventing a test from asserting that a body hasn't been sent.

Previously, we configured embedded Tomcat in such a way that no TLD
scan patterns were configured. This differed from a standalone
Tomcat installation where 4 patterns are configured that take
precedence over some of the skip patterns. The missing scan patterns
resulted in the skip patterns preventing the discovery of Log4j2's
TLDs.
This commit updates TomcatServletWebServerFactory to configure the
same four scan patterns as standalone Tomcat configures by default.
