[JBCACHE-964] Work committed: - Transforming Cache Loaders implemented and unit tests provided - migration folder structure. See JIRA. - build.xml modified to compile, jar, create manifest for migration jar and also added examples and migration jar to distros. - example created and tested; it includes readme.txt with details of the example and how to run it. Still TODO: - Unit tests for transforming cache loaders need to run from build.xml - Documentation for transforming cache loaders in users guide, what are they, when to use them,...etc. - Fix JBCACHE-877 that occurrs when unzipping JBossCache-core-2.0.0.BETA2.zip and running the examples. Workaround is to bring trove.jar into its lib. - Get examples/cacheloader-migration/build.sh working - Move JDBCCacheLoaderOld to the migration side. It's not that straightforward due to classes in /src having dependencies on it. Needs further study.
