Previously this method returned headers only when a Content-Type part header
was present. Now it is guaranteed to return headers (possibly empty) as long
as there is a MultipartFile or Part with the given name.

Prior to this commit, calls to setLocale() MockHttpServletResponse
would result in a NullPointerException if the supplied Locale was null.
Although the Javadoc for setLocale(Locale) and addHeader(String, String)
in javax.servlet.ServletResponse does not specify how a null
Locale should be handled, both Tomcat and Jetty simply ignore a null
value.
This commit therefore updates MockHttpServletResponse to silently
ignore a null Locale passed to setLocale().

Prior to this commit, calls to setHeader() and addHeader() in
MockHttpServletResponse would result in an IllegalArgumentException or
NullPointerException if the supplied header value was null.
Although the Javadoc for setHeader(String, String) and
addHeader(String, String) in javax.servlet.http.HttpServletResponse
does not specify how a null header value should be handled, both Tomcat
and Jetty simply ignore a null value. Furthermore,
org.springframework.http.HttpHeaders.add(String, String) declares the
headerValue parameter as @Nullable.
This commit therefore updates MockHttpServletResponse to silently
ignore null header values passed to setHeader() and addHeader().
Closes gh-26488
Prior to this commit, MockHttpServletResponse's setCharacterEncoding()
method did not update the contentType property, which violates the
Servlet 2.4 Javadoc for getContentType() and setCharacterEncoding().
This commit addresses this issue; however, some existing tests may have
to be updated as a result of this change.
For example, note how some of the tests in this commit have been
refactored to use MediaType##isCompatibleWith() instead of asserting
exact matches for the value returned by MockHttpServletResponse's
getContentType() method.
Closes gh-25536
Prior to this commit, calling reset() on MockHttpServletResponse did not
reset the `charset` field to `false` which could result in the
"Content-Type" header containing `;charset=null` which in turn would
result in errors when parsing the "Content-Type" header.
This commit resets the charset field to `false` in
MockHttpServletResponse's reset() method to avoid such errors.
Closes gh-25501
Prior to this commit, if the user supplied a comma-separated list such
as "en, it" as the Content-Language header value to
MockHttpServletResponse's setHeader() method, only the first language
was actually set in the response's Content-Language header (e.g., "en").
This commit ensures that all supplied content languages are set in the
response's Content-Language header.
Closes gh-25281
