This reverts commit d6df4a65 because running
gradle generatePomFileForMavenJavaPublication throws a
kotlin.KotlinNullPointerException error with Kotlin 1.5.20.

Revert Mockito upgrade done in 5d919dc0 because
Byte Buddy transitive upgrade from 1.11.1 to 1.11.3 seems to break Mockk tests
with java.security.AccessControlException related errors, so probably
better to wait Mockito using Byte buddy 1.11.5+ which seems to refine
this area, see https://github.com/raphw/byte-buddy/releases/tag/byte-buddy-1.11.5.

To slightly improve performance, this commit switches to
StringBuilder.append(char) instead of StringBuilder.append(String)
whenever we append a single character to a StringBuilder.

Prior to this commit, ConfigurationClass implemented equals(),
hashCode(), and toString(), but BeanMethod did not.

This commit introduces equals(), hashCode(), and toString()
implementations in BeanMethod for consistency with ConfigurationClass
to make it possible to use BeanMethod instances to index additional
metadata as well.

In order to properly implement equals() in BeanMethod, the method
argument types are required, but these are not directly available in
BeanMethod. However, they are available via ASM when processing @Bean
methods. This commit therefore implements equals(), hashCode(), and
toString() in SimpleMethodMetadata which BeanMethod delegates to.

For completeness, this commit also implements equals(), hashCode(), and
toString() in StandardClassMetadata, StandardMethodMetadata, and
SimpleAnnotationMetadata.

Closes gh-27076

Prior to this commit, the toString() implementation did not separate
method argument types with a comma or any form of separator, leading
to results such as:

    org.example.MyClass.myMethod(java.lang.Stringjava.lang.Integer)

instead of:

    org.example.MyClass.myMethod(java.lang.String,java.lang.Integer)

The SynchronossPartHttpMessageReader should only create temp directory

This commit defines the doc-root and api-spring-framework attributes
once in docs.gradle instead of duplicating them in each *.adoc file.

This commit also introduces a new docs-spring-framework global
attribute.

This commit disables the automatic header generation from Asciidoc's
default template and replaces it with a custom header that omits the
"Version" label before the revision number. The revision number is also
displayed in a simple span tag in order to reduce the amount of
vertical space taken by the header.

Prior to this commit, if a PathContainer was created using
Options.MESSAGE_ROUTE, DefaultPathSegment#parameters() returned a
mutable map which would allow the user to modify the contents of the
static, shared EMPTY_PARAMS map in DefaultPathContainer.

This commit prevents corruption of the shared EMPTY_PARAMS map by
ensuring that parameters stored in DefaultPathSegment are always
immutable.

This commit adds the missing `spring-framework-main-code` asciidoctor
attribute in the reference documentation.
