Before this commit, specifying the charset to use with produces or
consumes @RequestMapping attributes resulted in default charset
loss. That was really annoying for JSON for example, where using
UTF-8 charset is mandatory in a lot of use cases.
This commit adds a defaultCharset property to
AbstractHttpMessageConverter in order to avoid losing the
default charset when specifying the charset with these
@RequestMapping attributes.
It changes slightly the default behavior (that's why we have waited
4.3), but it is much more error prone, and will match with most
user's expectations since the charset loss was accidental in most
use cases (users usually just want to limit the media type supported
by a specific handler method).

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.

This commit speeds up the AntPathMatcher implementation by
pre-processing patterns and checking that candidates are likely
matches if they start with the static prefix of the pattern.
Those changes can result in a small performance penalty for positive
matches, but with a significant boost for checking candidates that don't
match. Overall, this tradeoff is acceptable since this feature is often
used to select a few matching patterns in a much bigger list.
This will lead to small but consistent performance improvements in
Spring MVC when matching a given request with the available routes.

This change updates all cases where callbacks are invoked to catch and
suppress errors (since there is not match to do with and error from
a callback be it success or failure).
Also updated is the contract itself to clarify this and emphasize the
callbacks are really notifications for the outcome of the
ListenableFuture not the callbacks themselves.

JDK8 and Apache Commons Codec support the RFC 4648
"URL and Filename Safe" Base64 alphabet.
Add methods to `Base64Utils` to support this feature.
This commit reworks the arrangement to a centralized cache, avoiding any extra reflection attempts if a cache entry is known already. In the course of this, it also enforces toXXX methods to be declared as non-static now (which is the only sensible arrangement anyway).
