  Consistent descriptions for ConfigurationClass

Previously, a ConfigurationClass created from AnnotationMetadata
and a ConfigurationClass created from a class would have subtly
different descriptions. Given a class named com.example.Foo, the
former’s description would be “com.example.Foo”, whereas the latter’s
description would be “class com.example.Foo”.

This commit updates ConfigurationClass to make the description
consistent, preferring the description without “class” in it.

Closes gh-970

The test failure was caused by the previous commit. The Message
resolver now supports payload conversion so it can raise a
MessageConversionException, not MethodArgumentTypeMismatchException.

Refine the optimizations made in 6f55ab69 in order to restore binary
compatibility and resolve a regression.

Tests of the form pathMatcher.match("/foo/bar/**", "/foo/bar") should
return true as this was the behavior in Spring 4.2.

The MessageMethodArgumentResolver now also supports applying a
MessageConverter to the payload.

This is effectively a shortcut for declaring a method with an @Payload
argument + MessageHeaders and then creating a new message from the two.

Commit ccd17d introduced a regression where a custom HTTP method
would no longer match for an empty @RequestMapping condition.

The previous behavior should now be restored. Effectively
RequestMethodRequestCondition as before will now match to any HTTP
method (even unknown/custom ones) if the methods condition is empty.
The only exception is HTTP OPTIONS for which we provide default
handling as a fallback (i.e. when not mapped explicitly).

This commit adds weak ETag support in ShallowEtagHeaderFilter.
This improves the behavior of the filter in tow ways:

* weak ETags in request headers such as `W/"0badc0ffee"` will be
compared with a "weak comparison" (matching both weak and strong ETags
of the same value)
* when enabled with the "writeWeakETag" init param, the filter will
write weak Etags in its HTTP responses

This change makes clear that this is the intent of the CacheControl API
not to provide a way to configure both "no-cache" and "no-store"
directives for the "Cache-Control" header.

Issue: SPR-13780

Check that the path is valid and resolvable before checking that the
http method is supported. For invalid or unresolvable paths, always
respond with a 404.

Use synchonous API for synchonous OkHttp requests

This commit changes the OkHttpClientHttpRequestFactory to use the
synchronous OkHttp API for non-async requests, as opposed to
synchronizing the async API (which it used to do).
