This commit introduces the Jackson2Tokenizer as a replacement for the
JsonObjectDecoder. The latter was dropped because of its complexity, and
hard dependency on Netty's ByteBuf.
The new Jackson2Tokenizer leverages the new non-blocking JSON parser,
using it to parse the incoming data buffers into TokenBuffers, each
token buffer representing one JSON object. As with JsonObjectDecoder,
it also supports streaming individual JSON array elements.

This commit introduces 2 new public methods in HttpHeaders in order
to leverage Java 8 ZonedDateTime in addition to the existing long
(with GMT time zone implied) variants:
- ZonedDateTime getFirstZonedDateTime(String headerName)
- void setZonedDateTime(String headerName, ZonedDateTime date)
This commit also leverages Java 8 thread-safe DateTimeFormatter for
HttpHeader implementation instead of SimpleDateFormat. As a consequence
of the usage of DateTimeFormatter.RFC_1123_DATE_TIME, HTTP date header
serialization could change slightly for single digit days from for
example "Thu, 01 Jan 1970 00:00:00 GMT" to
"Thu, 1 Jan 1970 00:00:00 GMT".

This new WebFilter implementation is designed to allow initial
CORS support when using WebFlux functional API. More high-level
API may be introduced later.
Issue: SPR-15567
Static parse methods on PathSegmentContainer and PathSegment plus:
isEmpty() on PathSegmentContainer and PathSegment
isAbsolute() and hasTrailingSlash() on PathSegmentContainer
char[] alternative for valueDecoded() on PathSegment
This commit introduces LocaleContextResolver interface, which is used
at ServerWebExchange level to resolve Locale, TimeZone and other i18n
related informations.
It follows Spring MVC locale resolution patterns with a few differences:
- Only LocaleContextResolver is supported since LocaleResolver is less
flexible
- Support is implemented in the org.springframework.web.server.i18n
package of spring-web module rather than in spring-webflux in order
to be able to leverage it at ServerWebExchange level
2 implementations are provided:
- FixedLocaleContextResolver
- AcceptHeaderLocaleContextResolver
It can be configured with both functional or annotation-based APIs.

Previously `HandlerMapping` implementation were heavily relying on
`String` path patterns, `PathMatcher` implementations and dedicated maps
for matching incoming request URL to an actual request handler.
This commit adds the `PathPatternRegistry` that holds `PathPattern`
instances and the associated request handler — matching results are then
shared as `PathMatchResult` instances. `AbstractUrlHandlerMapping` will
use this registry directly, but other components dealing with request
matching (like `PatternsRequestCondition`) will directly use ordered
`PathPattern` collections since ordering is important there.
This opens the door for faster request matching and simplifies the
design of this part.
Issue: SPR-15608
This commit enables trailing slash matching in `PathPatternParser` by
default - this mirrors the default configuration in `PathMatcher`
implementations in MVC.
The use of the undecoded URL path by default and the removal of suffix
pattern matching effectively means HttpRequestPathHelper is no longer
needed.

Introduce pathWithinApplication() in ServerHttpRequest and use it for
request mapping purposes instead of LookupPath.
In turn this means that for request mapping purposes:
1) the path is not decoded
2) suffix pattern matching is not supported
Issue: SPR-15640
Before this commit there was no special handling for URL encoding
of the path pattern string coming into the path pattern parser. No
assumptions were made about it being in an encoded form or not.
With this change it is assumed incoming path patterns are not
encoded and as part of parsing the parser builds PathPattern
objects that include encoded elements. For example parsing "/f o"
will create a path pattern of the form "/f%20o". In this form
it can then be used to match against encoded paths.
Handling encoded characters is not trivial and has resulted in
some loss in matching speed but care has been taken to
avoid unnecessary creation of additional heap objects. When
matching variables the variable values are return in a
decoded form. It is hoped the speed can be recovered, at least
for the common case of non-encoded incoming paths.
