Fix VCS remoting class loading issue with javax.transaction.xa.Xid objects

When having on client side an Xid object implementation which its class doesn't exist in the server classpath,
This is happening when Apogee (using vcs remote) is connected to a jboss server. The class org.apache.geronimo.transaction.manager.XidImpl that has been serialized and sent to the server can't be loaded in jboss.

The fix consist of creating a implementation of Xid that is known by the client and the server. This Xid object would take all the information from the original Xid object and replace it.
