<AWT Dev> 6890458: Datatransfer API should not require RMI to be present

[Alan Bateman]

Alexey Utkin - would you mind reviewing this?

I'd like to change the implementation of the AWT data transfer API so 
that it doesn't require RMI to be present. In other words, if the 
application is not using remote interfaces then it shouldn't matter if 
java.rmi.Remote is accessible or not and 
DataFlavor.isFlavorRemoteObjectType will always return false. If the 
application is using remote interfaces then it requires RMI to be 
present and everything works as it does now. The webrev with the changes 
is here:

I didn't find any tests that exercise this code in the jtreg/regression 
suite but Girish Ramachandran helped me on this so I'm confident that it 
doesn't introduce any regressions.

Thanks,
Alan.
