Summary: An Offline SplitParent Region can be assigned breaking

Affects Versions: 0.98.0, 0.95.1, 0.94.10
Reporter: Matteo Bertozzi
Assignee: Jimmy Xiang

An offline split parent region can be assigned by using 'assign' from shell.
This may trigger a compaction on the split parent region that should be
offline, breaking the references of the two daughters.
The easy way to test this is:
* disable compactions
* create a table and insert some row
* split
* shutdown the master (otherwise there's a state checked inside the
AssignmentManager)
* start the master
* assign the region marked as OFFLINE => true, SPLIT => true (the compaction
on region startup will probably break the reference of the two daughters)
