randstruct: opt-out externally exposed function pointer structs
Some function pointer structures are used externally to the kernel, like the paravirt structures. These should never be randomized, so mark them as such, in preparation for enabling randstruct's automatic selection of all-function-pointer structures. These markings are verbatim from Brad Spengler/PaX Team's code in the last public patch of grsecurity/PaX based on my understanding of the code. Changes or omissions from the original code are mine and don't reflect the original grsecurity/PaX code. Signed-off-by: Kees Cook <keescook@chromium.org>
