xfs: set and validate dir/attr block owners

There are a couple of significant changes that need to be made to the
directory and xattr code before we can support online repairs of those
data structures.

The first change is because online repair is designed to use libxfs to
create a replacement dir/xattr structure in a temporary file, and use
atomic extent swapping to commit the corrected structure.  To avoid the
performance hit of walking every block of the new structure to rewrite
the owner number before the swap, we instead change libxfs to allow
callers of the dir and xattr code the ability to set an explicit owner
number to be written into the header fields of any new blocks that are
created.  For regular operation this will be the directory inode number.

The second change is to update the dir/xattr code to actually *check*
the owner number in each block that is read off the disk, since we don't
currently do that.
