[RDBSS]
[RXCE]
Try to make use of wrapper more 'properly'. Now, we use wrappers for ASSERT and
memory management.
This allows us to allocate memory with low priority (which isn't supported by ReactOS
yet :-().
Note that we go a bit farther than MS: we also define RxFreePoolWithTag() and make use of
it.
This should make Thomas happy :-)
