* MxFile and implementations 100% match * Add MxFile and it's implementations, MxSystemFile and MxMemoryFile. The names are chosen by me, we don't know their original naming. * These expose a Read/Write/Seek/Tell interface for reading and writing data, either from a file on disk or memory buffer. * 100% match all functions. * Change name to LegoStream * Use p_ convention * Assert size
