On a Servlet container a completion notification may come at any time
even in the UNSUBSCRIBED state, i.e. before the write Publisher has
called onSubscribe.

Prior to this commit, the entry set of read-only HttpHeaders lost the
original headers' ordering.
The changes in commit ce7278aaf4 introduced a regression in the read-only
HttpHeaders support. Specifically, the implementation of entrySet() in
the internal ReadOnlyHttpHeaders class converted the original entry set
to an immutable, non-ordered set of immutable entries.
This commit fixes this issue by converting the original entry set to an
immutable, ordered set of immutable entries.
Closes gh-23551
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

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
Prior to Spring Framework 5.1.3, MimeTypeUtils.parseMimeTypes() and
MediaType.parseMediaTypes() ignored empty entries, but 5.1.3 introduced
a regression in that an empty entry -- for example, due to a trailing
comma in the list of media types in an HTTP Accept header -- would result
in a "406 Not Acceptable" response status.
This commit fixes this by filtering out empty entries before parsing
them into MimeType and MediaType instances. Empty entries are therefore
effectively ignored.
Fixes gh-23241
