Fix IBM management console to match coding standard

Lots of missing inline definitions, a case where a RVO move is not
guaranteed when returning a variant, and removing the header checks,
which means that these types of build errors wont happen in the future.

Tested:
Should be no impact, but could someone from the IBM team grab these
changes and sanity check them?
