Pulls out WildFly XA Recovery specifics into a different project. Some
XA recovery code is still present and is used as integration points for

https://issues.apache.org/jira/browse/ACTIVEMQ6-3
We are renaming packages from activemq6 to activemq as that's more generic and version independent
The previous commit renamed the directories. On this commit now I'm changing the code.
If we changed the code and the directories on the same commit git would remove and add a lot of files
without recognizing the renames.
