Implement ion_status_t behavior

[iondbproject]

ion_status_t is currently partially implemented. To fully implement ion_status_t, the following must be done:

• The return types of all affected methods need to be adjusted across the dictionary, handler, and implementation levels.
• Any unit test affected will also need to be changed to accommodate. Reading an err will now read the err member of the ion_status_t struct. These unit tests should also assert the rows affected is reported correctly.
• All implementations must properly support and return the struct, with rows affected.

This task has been done and is merged into development. See 99be250271afac701148f573d7573a577855b27e
