dvdisasm: Overhaul [O. Galibert]
Disassemblers are now independant classes. Not only the code is cleaner, but unidasm has access to all the cpu cores again. The interface to the disassembly method has changed from byte buffers to objects that give a result to read methods. This also adds support for lfsr and/or paged PCs.
