The complete Extended API stuff cannot be folded into Apache, although it
contains only generic hook stuff. Because the hooks _CAN_ be used for crypto,
so they will be considered as crypto hooks by others. Even when crypto is only
_one_ usage of them. So, the hook stubs cannot be folded into Apache, NO
CHANCE. But the hooks are implemented by src/ap/ap_hook.c and src/ap/ap_ctx.c
sources which contain totally generic code. This (without the usage of this
code inside src/main/buff.c, etc.) _COULD_ be folded into Apache. But only
this. Because this is only the implementation of a hook mechanism but not the
hooks itself.

As I said: The code which _implements_ the hook and context mechanism is
generic and IMHO could be folded into Apache. But the hooks itself (the hook
calls!) cannot be folded in. Because although they are generic hook calls,
they are intended for crypto stuff. So they will be considered crypto hooks.
