> RFC 4122 defines a UUID.  A GUID is the same as a UUID in string form, but differs in
binary layout.  Microsoft operates with GUIDs but confusingly labels them as UUIDs in their
documentation and include files.
> i.e. rpcdce.h:  typedef GUID UUID;
> The binary form matters since it is used over the wire.  Mapping a GUID to a UUID (or
vice versa) without the layout conversion results in structures with mangled RFC version info
and different string representations on Windows and non-Windows systems.
> Proton currently only calls Microsoft APIs to obtain the string representation of the
UUID (which will match the GUID), so it is unaffected.
