This commit removes the JUnit 4 dependency from all modules except
spring-test which provides explicit JUnit 4 support.
This commit also includes the following.
- migration from JUnit 4 assertions to JUnit Jupiter assertions in all
Kotlin tests
- migration from JUnit 4 assumptions in Spring's TestGroup support to
JUnit Jupiter assumptions, based on org.opentest4j.TestAbortedException
- introduction of a new TestGroups utility class than can be used from
existing JUnit 4 tests in the spring-test module in order to perform
assumptions using JUnit 4's Assume class

This commit migrates parameterized tests in spring-core using the
"composed @ParameterizedTest" approach. This approach is reused in
follow-up commits for the migration of the remaining modules.
For a concrete example, see AbstractDataBufferAllocatingTests and its
subclasses (e.g., DataBufferTests).
Specifically, AbstractDataBufferAllocatingTests declares a custom
@ParameterizedDataBufferAllocatingTest annotation that is
meta-annotated with @ParameterizedTest and
@MethodSource("org.springframework.core.io.buffer.AbstractDataBufferAllocatingTests#dataBufferFactories()").
Individual methods in concrete subclasses are then annotated with
@ParameterizedDataBufferAllocatingTest instead of @ParameterizedTest or
@Test.
The approach makes the migration from JUnit 4 to JUnit Jupiter rather
straightforward; however, there is one major downside. The arguments
for a @ParameterizedTest test method can only be accessed by the test
method itself. It is not possible to access them in an @BeforeEach
method (see https://github.com/junit-team/junit5/issues/944).
Consequently, we are forced to declare the parameters in each such
method and delegate to a custom "setup" method. Although this is a bit
cumbersome, I feel it is currently the best way to achieve fine grained
parameterized tests within our test suite without implementing a custom
TestTemplateInvocationContextProvider for each specific use case.
Once https://github.com/junit-team/junit5/issues/878 is resolved, we
should consider migrating to parameterized test classes.

Deprecate all mutation methods in `MethodParameter` in favor of factory
methods that return a new instance. Existing code that previously relied
on mutation has been updated to use the replacement methods.
Closes gh-23385
Added support for status codes that do not occur in HttpStatus in
DefaultClientResponseBuilder and made ClientResponse::statusCode
ClientHttpResponse::getStatusCode @Nullable.

The isJavaIdentifier check is not really required, but also seems
intuitive for variables to be Java identifier-like. This commit relaxes
the constraint a bit by also allowing "-".
Closes gh-23101
Prior to this commit, the `header(String, String)` method in the
ServerHttpRequest.Builder API actually added a header value instead of
setting or overriding a header value. Since this conflicted with the
stated behavior in the Javadoc as well as the original intention of the
method, we have decided to introduce an overloaded variant
`header(String, String...)` which accepts a var-args list of header
values to set or override.
In addition, this commit deprecates the existing `header(String, String)`
method for removal in Spring Framework 5.2.
In order not to be a breaking change for custom implementations of the
builder API, this commit implements the new `header(String, String...)`
method as an interface `default` method, with the intent to remove the
default implementation in Spring Framework 5.2

To make the switching of separators complete, it is also important to
know whether the decoding of path segment values and the parsing of
path param should be done as those are applied transparently.
This commit replaces the recently added separator argument to
PathContainer.parsePath with an Options type with two predefined
constants. One for HTTP URLs with automatic decoding and parsing of
path params, and another for "." separated message routes without
decoding except for encoded sequences of the separator itself.

Replace docs on using MultipartBodyBuilder for the RestTemplate with
examples that show MultiValueMap. Originally the idea was to make
MultipartBodyBuilder accessible to the RestTemplate too, but with
support for async parts that's no longer a good fit.
Closes gh-23295
OncePerRequestFilter now has a doFilter method that allows separate
processing of nested ERROR dispatches. This is useful for filters
that wrap the request and response.
Closes gh-23196
