/* Notes:
* Before you start changing something in this file be aware of the following:
*
* - There are several functions called recursively. In a very subtle and
* obscure way. DLLs can reference each other recursively etc.
* - If you want to enhance, speed up or clean up something in here, think
* twice WHY it is implemented in that strange way. There is usually a reason.
* Though sometimes it might just be lazyness ;)
* - In PE_MapImage, right before PE_fixup_imports() all external and internal
* state MUST be correct since this function can be called with the SAME image
* AGAIN. (Thats recursion for you.) That means MODREF.module and
* NE_MODULE.module32.
