Log:
[WS2_32]
- Turn the "!memcmp(ptr1, ptr2, sizeof(GUID))" into IsEqualGUID(ptr1, ptr2)
macro calls (aka. make code readable);
this also allowed me to discover a logical bug in the GUID comparison in
WsNcUpdateNamespaceList.
- Fix few comments, and rename some goto labels to make their meaning clearer (they are
not only taken for error code paths,
but also on regular path, for cleanup before returning from the function).
