Issue: SPR-11105

The tests introduced in this commit demonstrate the current lacking
support for composable stereotypes on interfaces (using @Transactional)
as a concrete example.

- Added explicit reference to “get” and “find” lookup types in the
  class-level Javadoc.
- Updated documentation for the underlying algorithms in
  findAnnotation(Method,Class) and findAnnotation(Class,Class) in line
  with the status quo.
- Reverted recent changes to findAnnotationDeclaringClass() by removing
  meta-annotation support in order to maintain backwards compatibility
  with previous releases.

Fix the reference documentation example for ConversionServiceFactoryBean
to use a `<set>` instead of a `<list>`.

* SPR-9164:
  Add BigDecimal support for SpEl numeric operations

Prior to this change, SpEL supported numeric operations for int, float,
ect. `new java.math.BigDecimal('0.1') > 0` evaluated to false
(BigDecimal is truncated to int)

This commit introduces support for BigDecimal operations for all
mathematical operators. `new java.math.BigDecimal('0.1') > 0` now
evaluates to true (the comparison is made with BigDecimals)

* fix-SPR-9194:
  Change SpEL equality operators to use .equals

Prior to this commit the SpEL operators `==` and `!=` were using the
Java `==` comparison operator as part of their equality checking. It is
more flexible to use the equals() method on Object.

Under this commit the change to .equals() has been made and the equality
checking code has been pushed into a common method in the Operator
superclass. This commit also makes some tweaks to the other operator
classes - the Float case was missing from OpGT.

Prior to this commit, the getValue(Annotation, String) method in
AnnotationUtils failed to retrieve the value of the desired annotation
attribute if the annotation itself was not public -- for example if the
annotation was declared as package private.

This commit addresses this issue by ensuring that getValue(Annotation,
String) uses reflection to make the desired annotation attribute method
accessible before attempting to invoke it to retrieve the value.

As of Gradle 1.8, ‘testReport true’ is deprecated. Thus in order to
generate TestNG reports alongside JUnit reports with Gradle 2.0 and
beyond, we are now using:

  getReports().getHtml().setEnabled(true)

Generate docbook xml from the asciidoc reference guide and use the
docbook-reference-plugin to generate HTML (single and multi-page) and
PDF documentation.

Remove the superfluous spaces that appear in the asciidoc source.

Issue: SPR-11096

Remove or replace broken links from the reference documentation.

Issue: SPR-11096

Remove the superfluous space that appears before each 'http' reference
in the asciidoc source. Presumably there due to some quirk of the
docbook conversion.

Issue: SPR-11096

Specify a specific asciidoc type of 'docbook' to prevent
'multiple titles at level 0' errors during generation.
