Includes efficient check for same ClassLoader in ClassUtils.isVisible, efficient MethodMatchers check for IntroductionAwareMethodMatcher, and supertype method resolution in MethodMapTransactionAttributeSource.

Prior to this commit, the various `HttpMessageConverter` instances
configured for a given `RestTemplate` instance could all contribute
`MediaType` values to the "Accept:" request header.
This could lead to duplicate media types in that request header,
cluttering for the HTTP request for no reason.
This commit ensures that only distinct values are added to the request.

This commit introduces a deferred initialization of the declared beans
in order to make it possible to access to the environment (and even
to the context for advanced use-cases) in the beans { } Kotlin DSL.

HandlerMethodReturnValueHandlerComposite and
AbstractMethodMessageHandler iterate using index over collections
implementing RandomAccess to avoid unnecessary iterators.
Using the simple example shown in the ticket but switching from
Mono<String> to Flux<String> (and 5,000,000 onNext calls) shows that
constant pausing causes significant overhead and is not worth the
trouble vs ignoring the onWritePossible in REQUESTED state.
Issue: SPR-16702
Undertow does not provide a way to check if we can write so with the
current implementation of isWritePossible, deep recursion can occur
when writing slows down. We now use a flag to keep track of write
ChannelListener callbacks.
This commit also addresses a related issue in
AbstractListenerWriteProcessor that went undected since #3c2d186
where after a large (single) buffer that is not written fully, the
completion signal is processed before the all data is written.
Issue: SPR-16702
Includes direct use of ControllerMethodInvocationInterceptor for return type Object, avoiding the attempt to generate an Object subclass.
Issue: SPR-16710
Spring's CGLIB fork is patched with local copies of affected files here, introducing the notion of a "contextClass" (e.g. the proxy superclass) which gets passed through to ReflectUtils.defineClass for delegating to MethodHandles.Lookup.defineClass eventually, against a privateLookupIn(contextClass) lookup context on JDK 9/10/11.

This commit documents the difference between configuring the socket
timeout on the `RequestConfig` and on the `SocketConfig`.
The first one does not affect timeouts when establishing an SSL
connection or sending a CONNECT request to a proxy. For these use cases,
it is required to configure `SocketConfig` on the `HttpClient` instance
directly.

Gradle 4.6 provides built-in support for the JUnit Platform within the
standard `test` task.
This commit configures a custom `testJUnitJupiter` test task for
executing JUnit Jupiter tests directly on the JUnit Platform instead of
indirectly on JUnit 4 via @RunWith(JUnitPlatform.class).
This switch provides for better integration with Gradle's test reporting
and paves the way for a possible transition to the JUnit Platform in the
future.
