[UDFS] Import a UDF File System Driver created by Alexander Telyatnikov (Alter) and co. Many thanks to Alexander Rechitskiy (jeditobe), the negotiator for opening the source of the whole software package (DVD Write Now) under the GPLv2 license and to the authors for kindly accepting to do so. I introduced many changes to the original code (made it use our PSEH3 for SEH, got it to compile from within ReactOS in both MSVC and Windows GCC builds...etc) and it's still WIP. We'll hopefully have an excellent collaboration to improve it and maintain its sync.. Stay tuned ;) CORE-9774 svn path=/trunk/; revision=68036
