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.

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.

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.

This commit replaces the use of Collections.unmodifiableList/Set/Map
with the corresponding 'of(...)' factory methods introduced in Java 9.

This commit refactors HttpMethod from a Java enum into a class. The
underlying reason being that HTTP methods are not enumerable, but
instead an open range and not limited to the predefined values in the
specifications.
Closes gh-27697
The current implementation suggests that the request's headers are not
expected to change. Hence, it's not necessary to copy them.
Furthermore, it might be costly to do so if there are many headers.
Instead, cache only the request's header names for method getHeaderNames.
Methods getHeader and getHeaders delegate to the respective methods of
request if the header name is not in FORWARDED_HEADER_NAMES. Otherwise,
they return null or an empty Enumeration respectively.
