Fix mapping of blocks using VAT when it is stored in an inode.
UDF_I(inode)->i_data already points to the beginning of VAT header so there's
no need to add udf_ext0_offset(inode).

This patch implements parsing of metadata partitions and reading of Metadata
File thus allowing to read UDF 2.50 media. Error resilience is implemented
through accessing the Metadata Mirror File in case the data the Metadata File
cannot be read. The patch is based on the original patch by Sebastian Manciulea
<manciuleas@yahoo.com> and Mircea Fedoreanu <mirceaf_spl@yahoo.com>.

We didn't handle VAT packed inside the inode - we tried to call udf_block_map()
on such file which lead to strange results at best. Add proper handling of
packed VAT as we do it with other packed files.

There's really no reason to keep udf headers in include/linux as they're
not used by anything but fs/udf/.

This patch merges most of include/linux/udf_fs_i.h into fs/udf/udf_i.h,
include/linux/udf_fs_sb.h into fs/udf/udf_sb.h and
include/linux/udf_fs.h into fs/udf/udfdecl.h.

The only thing remaining in include/linux/ is a stub of udf_fs_i.h
defining the four user-visible udf ioctls.  It's also moved from
unifdef-y to headers-y because it can be included unconditionally now.
