The URI template is now manually parsed vs using a regex to extract
URI variable names and to create a pattern for matching to actual URLs.
This provides more control to deal with nested curly braces.

The goal is to avoid String name comparisons in favor of annotation type identity checks wherever possible. Also, we avoid double getDeclaredAnnotations/getAnnotations checks on anything other than Classes now, since we'd just get the same result in a fresh array.

Improve the performance of the `getMergedAnnotationAttributes` and
`isAnnotated` methods in `AnnotatedElementUtils` by returning
immediately when the element had no annotations.

Add new MediaType.APPLICATION_JSON_UTF8 and
MediaType.APPLICATION_JSON_UTF8_VALUE constants for
"application/json;charset=UTF-8" content type in order to make it
easier to override @RequestMapping "produces" attribute without
losing the default JSON charset (UTF-8).

Refine the approach of having <mvc:view-resolvers> detect and use the
ContentNegotiationManager instance registered with
<mvc:annotation-driven> introduced in the last commit.
Issue: SPR-13559
The <mvc:annotation-driven> element now adds an alias when a
ContentNegotiationManager bean is registered with a custom name.
This helps <mvc:view-resolvers> to more reliably find such a custom
ContentNegotiationManager.

Prior to this change, serving resources with ResourceHttpRequestHandler
could result in NPE when requesting an existing folder located in a JAR.
This commit swallows those exceptions, as it is not possible to foresee
those cases without reading the actual resource. This result in a HTTP
200 response with a zero Content-Length instead of a HTTP 500 internal
exception.

Previously, the only way to add the collection converters to a registry
was to add *all* default converters. A new "addCollectionConverters"
public method is now available to only register them.
