Description:
We should add __attribute__((warn_unused_result)) to the Dictionary_client methods to make them harder to misuse.
This will give compilation warnings (GCC, Clang) if the API user ignores return values.

How to repeat:
Code inspection.

An attribute was added to data dictionary client method declarations to
generate compilation warnings when return values are ignored.
