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
DataSourceUtils moved to main core.io.buffer package.
Consistently named Jackson2JsonDecoder/Encoder and Jaxb2XmlDecoder/Encoder.
Plenty of related polishing.
This commit changes the reactive flushing mechanism to use a newly
introduced writeAndFlushWith(Publisher<Publisher<DataBuffer>>) on
ReactiveHttpOutputMessage instead of using the FlushingDataBuffer.

This commit makes use of the new Supplier<String> variants of utility
methods in org.springframework.util.Assert within the spring-core
module.
Issue: SPR-14450
Prior to this commit, utility methods in
org.springframework.util.Assert accepted String arguments for custom
error messages. Such Strings are evaluated (e.g., concatenated)
eagerly, and for performance reasons, it was therefore not always
possible to make use of these utility methods. Consequently, there are
several places in the code base that "inline" identical functionality
in order to lazily evaluate error message concatenation and avoid an
unnecessary performance penalty. This leads to verbose code like the
following.
if (!contextPath.startsWith("/")) {
throw new IllegalArgumentException("contextPath '" + contextPath +
"' must start with '/'.");
}
if (contextPath.endsWith("/")) {
throw new IllegalArgumentException("contextPath '" + contextPath +
"' must not end with '/'.");
}
This commit addresses this shortcoming by introducing Supplier<String>
variants of all utility methods in org.springframework.util.Assert that
allow custom error messages to be evaluated lazily via a lambda
expression that is only evaluated if the assertion fails. This results
in a simplification of the previous examples as follows.
Assert.isTrue(contextPath.startsWith("/"), () -> "contextPath '" +
contextPath + "' must start with '/'.");
Assert.isTrue(!contextPath.endsWith("/"), () -> "contextPath '" +
contextPath + "' must not end with '/'.");
