Description:
In 5.1 a field rename is done as a fast (non-copying) alter table.
In ndbcluster there is a local data dictionary dependent on have
correct names of fields when accessed directly from NDB API.

How to repeat:
Rename a field and try to use it from an application
using NDB API.

Suggested fix:
Add a flag so that the ndbcluster handler can
detect name change in method check_if_incompatible_data
and return that table should be copied.
