* referenced by another module have to be initialized before the module

* - the initialization routine of a DLL can itself call LoadLibrary,

* the 'old' modules) at any time during the whole process
*
* (Note that this routine can be recursively entered not only directly
* from itself, but also via LoadLibrary from one of the called initialization
* routines.)
*
* Furthermore, we need to rearrange the main WINE_MODREF list to allow
* the process *detach* notifications to be sent in the correct order.
* This must not only take into account module dependencies, but also
* 'hidden' dependencies created by modules calling LoadLibrary in their
* attach notification routine.
*
* The strategy is rather simple: we move a WINE_MODREF to the head of the
* list after the attach notification has returned. This implies that the
* detach notifications are called in the reverse of the sequence the attach
* notifications *returned*.
