Forward declarations make the code larger and rewrites harder. Harder as
they are often omitted from global changes. Remove forward declarations
which are not really needed, i.e. the definition of the function is
before its first use.

note this conflicts with commit 386a966f5ce71a0364b158c5d0a6971f4e418ea8
that currently sits in the powerpc tree. I think it's easy to resolve.

Other than that:
