This commit adds a new chain-based, interception contract to be used
with `WebClient`. This is the HTTP client equivalent of the `WebFilter`
contract already implemented in web reactive server.
A `ClientHttpRequestInterceptor` implementation can transform the
outgoing HTTP request (method, URI or headers) before delegating it to
the next interceptor in the chain, or bypass the request processing
altogether and return a (cached) HTTP response.

This commit handles range requests in `ResourceWebHandler`, using the
`ResourceHttpMessageWriter` configured within the handler.
This `WebHandler` will add a `HTTP_RANGE_REQUEST_HINT` writer hint
containing all the HTTP Range information of the request.
Issue: SPR-14664
This new `HttpMessageWriter` leverages the `ResourceRegionEncoder` to
write `ResourceRegion` to HTTP responses, thus supporting HTTP Range
requests.
Whenever possible, this message writer uses the zero copy support for
single range requests.
This `HttpMessageWriter` is never used directly, but is used as a
delegate by the `ResourceHttpMessageWriter`. When provided with the
`BOUNDARY_STRING_HINT`, the `ResourceRegionHttpMessageWriter`
adapts its behavior in order to write a single/multiple byte ranges.
Issue: SPR-14664
This commit adds the necessary infrastructure for the support of HTTP
Range requests. The new `ResourceRegionEncoder` can write
`ResourceRegion` objects as streams of bytes.
The `ResourceRegionEncoder` relies on an encoding hint
`BOUNDARY_STRING_HINT`. If present, the encoder infers that multiple
`ResourceRegion`s should be encoded and that the provided boundary
String should be used to separate ranges by mime boundaries.
If that hint is absent, only a single resource region is encoded.
Issue: SPR-14664
This commit makes it possible, in addition to provide hints, to
perform additional operations with the request and the response
at ServerHttpMessageReader/Writer level.
AbstractServerHttpMessageReader/Writer now provide
convenient beforeRead/beforeWrite abstract methods for such need.

Resetting the connection first before invoking a failure callback on
the application handler ensures that any checks to isConnected will
return false.
Issue: SPR-14721
This commit overrides the `checkResource` implementation in
`ScriptTemplateView` in order to check if the template file resource is
available and if the resolver can then proceed with rendering the
template.

In order to simplify configuration for use cases involving @Bean where
only a bean name or aliases are supplied as an attribute, this commit
introduces a new 'value' attribute that is an @AliasFor 'name' in @Bean.

Move the AbstractServletHttpHandlerAdapterInitializer together with
the other two base classes in spring-web-reactive. Since the
interface is in the web package, this avoids a package cycle.
Also add a mention in the reference.
Issue: SPR-14713
This commit introduces three new WebApplicationInitializers for use with
Spring Web Reactive:
- The AbstractServletHttpHandlerAdapterInitializer registers a
ServletHttpHandlerAdapter that wraps a user-provided HttpHandler.
- The AbstractDispatcherHandlerInitializer registers a
ServletHttpHandlerAdapter that wraps a DispatcherHandler (or any
WebHandler). The handler is provided with an application context.
- The AbstractAnnotationConfigDispatcherHandlerInitializer is a
subclass of the above, creating an
AnnotationConfigApplicationContext based no provided @Configuration
classes.

This commit extracts the response body insertion logic into a separate
strategy interface: BodyPopulator. Standard populators can be found in
BodyPopulators.
This commit refactors the Router into a RoutingFunctions class, by:
- Renaming the class :)
- Moving all Configuration logic into a separate, top-level
Configuration class with mutable builder.
