This commit fixes an issue in StringDecoder, where, if the buffer did
not contain any delimiters, it was released before it was relayed to
any subscribers.

This commit introduces Micrometer as an API dependency to the
spring-webflux module. Micrometer is used here to instrument `WebClient`
and record `Observation` for HTTP client exchanges.
This replaces Spring Boot's `MetricsWebClientFilterFunction` which
instruments `WebClient` via an `ExchangeFilterFunction`. Here, a direct
instrumentation is more efficient and less prone to metrics errors.

As of Java 18, the serial lint warning in javac has been expanded to
check for class fields that are not marked as `Serializable`.
See https://www.oracle.com/java/technologies/javase/18all-relnotes.html#JDK-8202056
In the Spring Framework codebase, this can happen with `Map`, `Set` or
`List` attributes which are often assigned with an unmodifiable
implementation variant. Such implementations are `Serializable` but
cannot be used as field types.
This commit ensures that the following changes are applied:
* fields are marked as transient if they can't be serialized
* classes are marked as `Serializable` if this was missing
* `@SuppressWarnings("serial")` is applied where relevant
Prior to this commit, several tests used ClassPathResource#getPath()
based on the knowledge that the ClassPathResource had been created
using the ClassPathResource(String,Class) constructor. However, making
such an assumption seems ill advised in light of the abstraction that
ClassPathResource provides.
In light of that, this commit avoids questionable use of
ClassPathResource#getPath() in tests by refactoring those tests to use
the proper abstractions provided by ClassPathResource.
This commit introduces support for Netty 5's Buffer, in the form of
Netty5DataBuffer. Because of the new API offered by Buffer, several
changes have been made to the DataBuffer API:
- CloseableDataBuffer is a simpler alternative to PooledDataBuffer, and
implemented by Netty5DataBuffer. DataBufferUtils::release can now
handle CloseableDataBuffer as well as PooledDataBuffer.
- PooledDataBuffer::touch has been moved into a separate interface:
TouchableDataBuffer, which is implemented by Netty5DataBuffer.
- The capacity of DataBuffers can no longer be reduced, they can only
grow larger. As a consequence, DataBuffer::capacity(int) has been
deprecated, but ensureWritable (formally ensureCapacity) still exists.
- DataBuffer::slice and retainedSlice have been deprecated in favor of
split, a new method that ensures that memory regions do not overlap.
- DataBuffer::asByteBuffer has been deprecated in favor of toByteBuffer,
a new method that returns a copy, instead of shared data.
- DataBufferFactory::allocateBuffer has been deprecated in favor of
allocateBuffer(int).

Not all HttpHeaders implementations are serializable. This commit
ensures that WebClientRequestException and WebClientResponseException
are serializable, by copying any non-serializable HttpHeaders into a
new, serializable, instance.

Prior to this commit, tests in these two classes intermittently failed
with errors similar to the following, due to concurrent modification
of shared files.
expected:
"<input type="text" id="name" name="name" value="Darren" >"
but was:
"<input type="text" id="name" name="name" value="Darren" >
"hidden"/>"
This commit fixes this by creating a new temporary folder for each test
method invocation.
