I appended a diff for review. Is this kind of interface ok?
This is kind of not a patch to apply, rather I want to avoid to put
effort in it and you telling me later I am too intrusive...:). So
can you give a ok or comment...

Interface so far:
struct preprocess_hook {
	def      : called when #define is processed
	args_beg : called before argument expasnion
	args_end : called after argument expasnion
	body_beg : called before body expansion
	body_end : called after body expansion
	post     : called after preprocess
};
All of there I found are needed. There might be more to be added...

I also introduce a tokentype TOKEN_M_EMPTY so that I can track
empty expansion. To filter these out again I add the post hook.
