When using a `RestTemplate` instance within a Spring MVC application,
client exceptions may propagate in the MVC stack and can be wrongly
mapped by server `ExceptionHandlers`, leading to a wrong HTTP response
sent to the MVC client.
The `RestTemplate` instance uses `HttpMessageConverter` to decode
the remote service responses; and when those fail decoding an HTTP
response, they can throw an `HttpMessageNotReadableException`. That
exception then bubbles up through the `HttpMessageConverterExtractor`,
`RestTemplate` and the whole MVC stack, later mapped to HTTP 400
responses, since those exceptions can also be throws by the server stack
when the incoming requests can't be deserialized.
This commit wraps all `IOException` and `HttpMessageNotReadableException`
instances thrown by the extractor into `RestClientException`` instances.
It's now easier to consistently handle client exceptions and avoid such
edge cases.

This change adds support for a target type in JsonPath assertions in
Spring MVC Test.
The existing assertValue(String expression, Object expectedValue)
transparently falls back on using an alternative JsonPath API that
allows specifying the target type to coerce to.
There is also a new overloaded method
assertValue(String expression, Matcher<T> matcher, Class<T> targetType)
for use with Hamcrest matchers where the target type can be specified.

HttpEntityMethodProcessor should not throw IllegalArgumentExceptions for
invalid If-None-Match headers.
For those cases, this commit makes sure that both
`HttpEntityMethodProcessor` and `ServletWebRequest` have a consistent
behavior and stop processing the request as conditional and leave the
handler handle it.

This commit sorts `ClientHttpRequestInterceptor`s when those are set in
`InterceptingHttpAccessor` (which `RestTemplate` extends from).
Interceptors can now be annotated with `@Order` or implements `Ordered`
to reflect their order of execution for each request.

This commit adds support for HTTP header field parameters encoding, as
described in RFC5987.
Note that the default implementation still relies on US-ASCII encoding,
as the latest rfc7230 Section 3.2.4 says that:
> Newly defined header fields SHOULD limit their field values to
US-ASCII octets
Issue: SPR-14547
Prior to this commit, extracting an HTTP response with an empty body
and no Content-Type header using the WebClient would:
* trigger the use of the Jackson2JsonDecoder
* throw a NoSuchElementException because of the use of `Flux.single()`
This commit changes this behavior to `Flux.singleOrEmpty()` to avoid
throwing exceptions for empty Flux instances.

Since the upgrade to Gradle 3, our Bamboo build is failing because it
can't find test reports "at the usual location".
This commit restores the location that Gradle 2 was using until we
upgrade to a version of Bamboo that supports it.

Previously the IDE (STS) was resolving a different reactor-core
version (3.0.0.BUILD-SNAPSHOT) than the build (3.0.0.RELEASE). This
discrepancy was due to the fact that reactor-netty now brings in
reactor-core 3.0.0.RELEASE. Gradle's version conflict resolution is to use
the latest version. However, the optional dependency on reactor-core
3.0.0.BUILD-SNAPSHOT was making the build path of the IDE use the SNAPSHOT.
This fix leverages a resolutionStrategy to ensure a consistent version of
reactor-core is used throughout the entire project. It also bumps up the
reactor-core version to 3.0.0.RELEASE to be consistent with reactor-netty.
Care is taken to only change 3.x vesion since 2.x is still used within
the codebase.
