possible change to upgrade tests

[Kathey Marsden <km...@sbcglobal.net>]

Are there any objections removing the lib directory from the upgrade 
tests expected path for old jars?  Currently the tests  require a system 
property be set. derbyTesting.oldReleasePath expecting releases to be 
under that path in ${derbyTesting.oldReleasePath}/M.m.f.p/lib

If we drop the lib we can use the format as it sits at:
https://svn.apache.org/repos/asf/db/derby/jars/ 
<https://svn.apache.org/repos/asf/db/derby/jars/>

so we could make an externals link to a standard location.

If noone objects I'll change it Monday.

Thanks

Kathey
