Clean readability-redundant-declaratio clang-tidy warnings

Function prototypes were declared twice for the FFIO framework, probably
because FFIO at some point during development existed as a separate
file. With this commit the second set of function prototypes is removed
leaving only the first entry at the top of the file. Similarly duplicate
header inclusions has been removed.
