Prior to this commit, `ResourceTransformerSupport.toAbsolutePath`
would call `StringUtils.applyRelativePath` in all cases. But this
implementation is prepending the given path even if the relative path
starts with `"/"`.
This commit skips the entire operation if the given path is absolute,
i.e. it starts with `"/"`.

Prior to this commit, the `ResourceUrlEncodingFilter` would wrap the
response and keep a reference to the request. When
`HttpServletResponse.encodeURL` is later called during view rendering,
the filter looks at the request and extracts context mapping information
in order to resolve resource paths in views.
This approach is flawed, when the filter is used with JSPs - if the
request is forwarded to the container by the `InternalResourceView`,
the request information is overwritten by the container. When the view
is being rendered, the information available in the request is outdated
and does not allow to correctly compute that context mapping
information.
This commit ensures that that information is being extracted from the
request as soon as the `ResourceUrlProvider` is set as a request
attribute.

The fix for SPR-17178 switched from debug to warn level warning for
all sub-classes of AbstractHandlerExceptionResolver where the request
concerned the DefaultHandlerExceptionResolver only.
This commit restores the original DEBUG level logging that was in
AbstractHandlerExceptionResolver from before SPR-17178. In addition
DefaultHandlerExceptionResolver registers a warnLogCategory by default
which enables warn logging and hence fulfilling the original goal
for SPR-17178.
Issue: SPR-17383
This reverts commit 162112.
Instead we'll go for a bigger rollback of the change from SPR-17178 so
that only DefaultHandlerExceptionResolver does warn logging by default.

1. Helper method to eliminate duplication in formatting (de-)serialized
values for logging introduced with prior commit #e62298.
2. Helper method for TRACE vs DEBUG logging with different details.
Issue: SPR-17254
At DEBUG show up to 100 chars, at TRACE show full formatted value.
Note that the formatValue helper method is duplicated a number of times
in this commit. A utility method will likely be added in spring-core
through an extra commit.

This commit represents a best effort attempt at fixing remaining
"a" vs. "an" grammatical errors related links specified via a fully
qualified class name.

This commit handles "empty" cases for `ResponseEntity` controller
handler return types when wrapped with a `java.util.Optional` in Spring
MVC or a single `Publisher` like `Mono`.
Given the following example for Spring MVC:
```
@GetMapping("/user")
public Optional<ResponseEntity<User>> fetchUser() {
Optional<User> user = //...
return user.map(ResponseEntity::ok);
}
```
If the resulting `Optional` is empty, Spring MVC will infer a
`ResponseEntity` with an empty body and a 404 HTTP response status.
The same reasoning is applied to Spring WebFlux with Publisher types:
```
@GetMapping("/user")
public Mono<ResponseEntity<User>> fetchUser() {
Mono<User> user = //...
return user.map(ResponseEntity::ok);
}
```
This feature is only valid for `HttpEntity` return types and does not
apply to `@ResponseBody` controller handlers.

This commit allows to specify a custom CorsConfigurationSource
in AbstractHandlerMapping (both Servlet and Reactive variants).
AbstractHandlerMapping#getCorsConfigurations method is now
deprecated.
