[PATCH] isofs includes sanitized

fs/isofs includes trimmed down to something resembling sanity.

Kernel-only parts of linux/iso_fs.h and entire linux/iso_fs_{sb,i}.h
moved to fs/isofs/isofs.h.

A lot of useless #include in fs/isofs/*.c killed.

-/* Every directory can have many redundant directory entries scattered
- * throughout the directory tree.  First there is the directory entry
- * with the name of the directory stored in the parent directory.
- * Then, there is the "." directory entry stored in the directory
- * itself.  Finally, there are possibly many ".." directory entries
- * stored in all the subdirectories.
- *
- * In order for the NFS get_parent() method to work and for the
- * general consistency of the dcache, we need to make sure the
- * "i_iget5_block" and "i_iget5_offset" all point to exactly one of
- * the many redundant entries for each directory.  We normalize the
- * block and offset by always making them point to the "."  directory.
- *
- * Notice that we do not use the entry for the directory with the name
- * that is located in the parent directory.  Even though choosing this
- * first directory is more natural, it is much easier to find the "."
- * entry in the NFS get_parent() method because it is implicitly
- * encoded in the "extent + ext_attr_length" fields of _all_ the
- * redundant entries for the directory.  Thus, it can always be
- * reached regardless of which directory entry you have in hand.
- *
- * This works because the "." entry is simply the first directory
- * record when you start reading the file that holds all the directory
- * records, and this file starts at "extent + ext_attr_length" blocks.
- * Because the "." entry is always the first entry listed in the
- * directories file, the normalized "offset" value is always 0.
- *
- * You should pass the directory entry in "de".  On return, "block"
- * and "offset" will hold normalized values.  Only directories are
- * affected making it safe to call even for non-directory file
- * types. */
