Allow packages to be split across projects which will be merged into a
single JAR file.
Make split package detection a dependency of the 'check' task. This
is idiomatic gradle as well as allowing the 'test' task (another
dependency of 'check') to be executed without split packages being
detected.
Omit the project spring-instructment-tomcat from the check on the basis
of SPR-10150.

Split packages are a well-known anti-pattern for OSGi and a blocker for
Eclipse Virgo (which prevents split packages being accessed via its
Import-Library construct).
Split packages are also unhelpful with a traditional linear classpath
as a split package name does not uniquely identify the Spring framework
JAR from which it came, thus complicating problem diagnosis and
maintenance.
Juergen Hoeller supports this position in the following comment in
SPR-9990:

Split packages have crept into Spring framework twice in recent months
- see SPR-9811 and SPR-9988. Currently, they are only detected once
the Spring framework has been converted to OSGi bundles and these
bundles have been tested with Eclipse Virgo.
This commit adds a build-time check for split packages to the Spring
framework build.

Prior to this commit, the following compilation error presented itself
when importing buildSrc ('spring-build-src') into Eclipse:
Groovy:missing type for constructor call @ line 36, column 49.
This commit replaces the use of the diamond operator with typical
generics syntax in order to work around the problem. It is assumed that
the underlying problem is to do with the Groovy compiler in use. This
change ensures that any contributor / committer importing
spring-framework into Eclipse has a straightforward experience without
being required to tweak Groovy settings.
If selection of the correct Groovy compilation settings can be made
automatic, then we should of course feel free to use Java 7-style syntax
there in the future.
Note that this was *not* a problem when importing buildSrc into IDEA 12.
Develop a gradle plugin to automatically update testCompile dependencies
to include the test source sets of project dependencies.
Allows the gradle build to more closely mirror the way that tests run
inside eclipse.
Previously the 'merge from' project's configurations exclude rules were
not used in the dynamically created 'merge into' project configurations.
This meant that the pom generation for 'merge into' project did not
exclude the dependencies from the 'merge from' project's configuration
excludes.
Now the exclude rules are copied into the dynamically created
'merge into' project's configurations.
