Fix MockHttpServletResponse HTTP status update

Prior to this commit, one could call the setStatus method on
this Mock object and update the response's status,
even though the sendError method had already been called.

According to the HttpServletResponse Javadoc, sendError() methods
commit the response; so the response can't be written after that.

This commit fixes MockHttpServletResponse's behavior; setStatus
methods do not update the status once the response has been
committed.

Add doesNotExist match to HeaderResultMatchers

Prior to this commit, one could not test for the absence of
a specific HTTP header in a response.
Using header("X-Custom-Header", Matchers.nullValue()) would not
work because it tests for an empty value of an existing header.

This commit adds a doesNotExist method on the
HeaderResultMatcher.

Revert resource handling changes

This change reverts recent commits made to expand the resource handling
mechanism in Spring MVC. The changes will move into a separate branch
and likely into a separate project allowing it to mature and evolve
without being tied to the main framework release schedule.

Support AntPathMatch URLs in URL ResultMatchers

Prior to this commit, one could only match exact URLs in redirectedUrl
and forwardedUrl ResultMatchers. When creating a resource with
a REST service, URLs often contain the id the new resource,
like "/resource/12".

This commit updates those ResultMatchers to support both
exact matches and AntPath matches, using new methods.
The former URL then can be tested against "/resource/*" in MVC tests.
