This commit also removes the corresponding deprecated Servlet MVC variant and updates DispatcherServlet.properties to point to RequestMappingHandlerMapping/Adapter by default.

Prior to this commit, the latest optimizations introduced in SPR-13913
would prevent matching when patterns contained spaces. Indeed, the
optimized path would not fully tokenize the paths nor trim the tokens,
as the "longer" code path does.
This commit disables this optimized path when the `trimTokens` option is
set to `true`.
Also, the `trimTokens` setting is now set to `false` by default.

Prior to this commit, the `ResourceHttpMessageConverter` would support
all HTTP Range requests and `MethodProcessors` would "wrap" controller
handler return values with a `HttpRangeResource` to support that use
case in Controllers.
This commit refactors that support in several ways:
* a new ResourceRegion class has been introduced
* a new, separate, ResourceRegionHttpMessageConverter handles the HTTP
range use cases when serving static resources with the
ResourceHttpRequestHandler
* the support of HTTP range requests on Controller handlers has been
removed until a better solution is found

Prior to this commit, the new match algorithm wouldn't work for multiple
consecutive path separators.
This commit separately matches path segments and path separators and
allows for multiple, consecutive path separators.

Prior to this commit, the size of the ApplicationContext cache in the
Spring TestContext Framework could grow without bound, leading to
issues with memory and performance in large test suites.
This commit addresses this issue by introducing support for setting the
maximum cache size via a JVM system property or Spring property called
"spring.test.context.cache.maxSize". If no such property is set, a
default value of 32 will be used.
Furthermore, the DefaultContextCache has been refactored to use a
synchronized LRU cache internally instead of a ConcurrentHashMap. The
LRU cache is a simple bounded cache with a "least recently used" (LRU)
eviction policy.

Prior to this commit, HTTP clients relying on the JDK HTTP client would
not properly reuse existing TCP connections (i.e. HTTP 1.1 persisten
connection). The SimpleClientHttpResponse would close the actual connection once the
response is handled.
As explained in the JDK documentation
(http://docs.oracle.com/javase/8/docs/technotes/guides/net/http-keepalive.html)
HTTP clients should do the following to allow resource reuse:
* consume the whole HTTP response content
* close the response inputstream once done
This commit makes sure that the response content is
totally drained and then the stream closed (and not the connection).
