split iso.h into two parts: iso.h (which now contains _only_ definitions 

about ISO9660 file system structure), and cd9660_extern.h (which now
contains the definitions and data structures used by the kernel).
There's lots of other stuff scattered around this code that should go
into cd9660_extern.h, but doesn't need to right now.  This changed patterned
on ffs, which has 'fs.h' which describes the FS structure, and ffs_extern.h
for kernel-internals gunk.  Now libsa can include iso.h without the nasty
hack that was there before.
