BIG REORGANIZATION.

Browse Source 
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.
