Move the AbstractServletHttpHandlerAdapterInitializer together with
the other two base classes in spring-web-reactive. Since the
interface is in the web package, this avoids a package cycle.
Also add a mention in the reference.

This commit adds Smile and CBOR Jackson HttpMessageConverters
and make it possible to create Smile and CBOR ObjectMapper via
Jackson2ObjectMapperBuilder, which now allows to specify any
custom JsonFactory.
Like with JSON and XML Jackson support, the relevant
HttpMessageConverters are automaticially configurered by
Spring MVC WebMvcConfigurationSupport if jackson-dataformat-smile
or jackson-dataformat-cbor dependencies are found in the classpath.

Since we have a dedicated section regarding Ehcache that is only
applicable to Ehcache 2.x, this commit clarifies that Ehcache 3.x is
JSR-107 compliant and the JCache support should be used with it
rather than attempting to configure the Ehcache 2.x support.
Commit 240f254 has introduced support for `java.util.Optional` in the
cache abstraction. If such type is present, the contained value is cached
if it is present.
This new feature slightly changed the semantic of `#result` that was
documented up till this commit as the "return value of the method
invocation". This is no longer true as `#result` for `Optional<T>`
refers to the `T` instance and not the `Optional` instance.
This commit clarifies both the javadoc and the documentation.

This commit removes `GuavaCache` and support classes. Caffeine supersedes
the caching support in the Google Guava library with an actively maintained
Java 8+ version in standalone form.
As it is the only Guava feature Spring framework integrates with, this
commit removes effectively any reference to Guava.
