This commit checks that a "Content-Length" request header isn't already
present before adding one in `Netty4ClientHttpRequestFactory`.
`HttpMessageConverter` implementations can write that request header so
the Netty request factory should only write that value when the header
is missing.
If that header is not written (and since we're not dealing with
the HTTP exchange in a chunked-based fashion), the HTTP client might not
send the request body at all.

This commit ensures that the `PathPatternParser` and the associated
cache map are used in a threadsafe fashion, since the PathMatcher
instance can be used for concurrent requests.
Issue: SPR-15246
This commit reduces the exposition of `PathPattern` instances throughout
the `HandlerMapping` API and removes some methods from its public API.
Issue: SPR-14544
Since the introduction of `PathPatternRegistry`, the various path match
configuration flags are no longer needed in several places and that
configuration can live in the registry itself.
Issue: SPR-14544
This commit adds the new `PathPatternRegistry`, which holds a
sorted set of `PathPattern`s and allows for searching/adding patterns
This registry is being used in `HandlerMapping` implementations and
separates path pattern parsing/matching logic from the rest. Directly
using `PathPattern` instances should improve the performance of those
`HandlerMapping` implementations, since the parsing and generation of
pattern variants (trailing slash, suffix patterns, etc) is done only
once.

Without this change the /{*foobar} and /** path elements were
not correctly enforcing that the first character they encounter
must be a separator. This problem was introduced when adjusting
the generated path element chains for these constructs. Originally
the generated chain included a SeparatorPathElement but in order for
these to match 'nothing' (i.e. /foo matches /foo/{*foobar}) the separator
path element was removed, so the separator enforcement needed moving
into the CaptureTheRestPathElement and WildcardTheRestPathElement.

This commit introduces a PathPatternParser which parses request pattern
strings into PathPattern objects which can then be used to fast
match incoming string paths. The parser and matching supports the syntax
as described in SPR-14544. The code is optimized around the common usages
of request patterns and is designed to create very little transient
garbage when matching.

This commit introduces JSON streaming support which
consists of serializing HTTP request with
application/stream+json media type as line delimited JSON.
It also optimize Flux serialization for application/json by
using flux.collectList() and a single Jackson invocation
instead of one call per element previous strategy.
This change result in a x4 throughput improvement
for collection with a lot of small elements.

The base URI is ignored for requests that include a host.
WebClient exposes UriBuilder (rather than UriBuilderFactory) for
per-request URI building based on the base URI. That provides
full control to add or replace components of the base URI.
This commit *adds* the "intercepted" headers to the ClientHttpRequest,
as opposed to replacing them, which is what happened before this commit.
Issue: SPR-15166
Following on the introduction of the UriBuilderFactory and its
DefaultUriBuilderFactory implementation, this commit deprecates
DefaultUriTemplate (and AbstractUriTemplateHandler).
The new DefaultUriBuilderFactory has comparable functionality and is
more flexible but cannot be merged into the existing hierarchy and
be backwards compatible with regards to protected methods.

Introduce separate adapters TomcatHttpHandlerAdapter/JettyHttpHandlerAdapter
so that each adapter can use the Tomcat/Jetty APIs for reading/writing
with ByteBuffer.
