When aborting an online add column
(e.g due to resource problems on 1-node, but not others)

Suggested fix:
Cleanup the code (which was very hairy)

      ndb - merge bug#47364 into 7.0, enabling testcase since it now actually works

pushed to 7.0.8 and 7.1
(also to 6.3, but there it does not solve "full" problem)

Documented bugfix in the NDB-7.0.8 changelog as follows:

        Aborting an online add column (for example, due to resource
        problems on a single data node, but not others) could lead to a
        forced node shutdown.

Closed.
