Initial commit of the new BaseFile implementation. It provides a common ground for file objects across platforms and divides responsibilities between the Common::File class and a base file implementation.

Also rearranged the factories into a new directory for clarity.

Note 1: The posix-file.h and cpp files are for testing only. Only the ds, ps2 and symbian architecture will use special BaseFile based objects.

Note 2: The current code does not yet make use of this new structure, since the Common::File remains intact.
