SocketUtils was introduced in Spring Framework 4.0, primarily to assist
in writing integration tests which start an external server on an
available random port. However, these utilities make no guarantee about
the subsequent availability of a given port and are therefore
unreliable. Instead of using SocketUtils to find an available local
port for a server, it is recommended that users rely on a server's
ability to start on a random port that it selects or is assigned by the
operating system. To interact with that server, the user should query
the server for the port it is currently using.
SocketUtils is now deprecated in 5.3.16 and will be removed in 6.0.

In a small minority of cases, the multipart boundary can spread across
three incoming buffers.
Prior to this commit, MultipartParser.BodyState only supported two
buffers. If the boundary is spread across three buffers, the first
buffer of the three is sent as a whole, even though it contains the
first bytes of the boundary.
This commit fixes this bug, by enqueuing all prior buffers in a queue,
and emitting the ones that cannot contain boundary bytes.

The failing test is for Apache HttpComponents where we cannot apply the
Content-Length together with other headers, and must pass it instead
explicitly to ReactiveEntityProducer when writing at which point it gets
set in the native headers.
Closes gh-27768
NettyHeadersAdapter::putAll uses HttpHeaders::add, which does not
overwrite existing headers. putAll should use HttpHeaders::set instead,
just like NettyHeadersAdapter::put does.

Where unfeasible, this commit adds inline comments to explain why
try-with-resources must not be used in certain scenarios. The purpose
of the comments is to avoid accidental conversion to try-with-resources
at a later date.
Closes gh-27823
With JDK 9, java.util.regex.Matcher received overloaded variants of
appendReplacement() and appendTail() that accept a StringBuilder,
allowing us to replace the use of StringBuffer with StringBuilder.
Closes gh-27822
This commit replaces the use of Collections.unmodifiableList/Set/Map
with the corresponding 'of(...)' factory methods introduced in Java 9.
