Attaching v5 patch set. 0001 - No change. 0002 - I moved the tests to
001_rep_changes.pl so that we could avoid creation of subscriber,
publisher nodes and other set up. I also added the multiple
publication for the subscription test case which was failing with
v2-0001 patch. Note that I had to create subscriber,  publications for
this test case, because I couldn't find the regression (on v2-001
patch) with any of the existing test cases and also I'm dropping them
after the test so that it will not harm any existing following tests.
Hope that's okay. With v5-0002 and v2-0001, the multiple publication
for the subscription test case fails.

Please consider the v5 patch set for further review.
