Subject: Add extra argument to substitute_hook_functions and interpose_imports
 for use with unhooking.

I think we'll need to explicitly record trampoline locations to avoid
the possibility of stomping on someone else's stuff if the function was
re-patched...

Also, document substitute_hook_functions.
