BIG REORGANIZATION.

Reorganize directory structure for inclusion of cd-paranoia. Works for GNU/Linux. Other OS's may be broken. Regression test output needs to be adjusted too. Move: lib/driver (split off of lib) lib/iso9660 (split off of lib) Add from paranoia: lib/cdda_interface lib/paranoia src/paranoia Also made some small changes to capability indentification to show more reading capabilties and show that. cd-info now shows the total disc size.
