To be consistent with the directory code, the attr code should use
unsigned names. Convert the names from the vfs at the highest level
to unsigned, and ænsure they are consistenly used as unsigned down
to disk.

Add a flags argument to struct xattr_handler and pass it to all xattr
handler methods. This allows using the same methods for multiple
handlers, e.g. for the ACL methods which perform exactly the same action
for the access and default ACLs, just using a different underlying
attribute. With a little more groundwork it'll also allow sharing the
methods for the regular user/trusted/secure handlers in extN, ocfs2 and
jffs2 like it's already done for xfs in this patch.
Also change the inode argument to the handlers to a dentry to allow
using the handlers mechnism for filesystems that require it later,
e.g. cifs.

This patch rips out the XFS ACL handling code and uses the generic
fs/posix_acl.c code instead. The ondisk format is of course left
unchanged.
This also introduces the same ACL caching all other Linux filesystems do
by adding pointers to the acl and default acl in struct xfs_inode.

These days most of the attributes in struct inode are properly kept in
sync by XFS. This patch removes the need for vn_revalidate completely by:
- keeping inode.i_flags uptodate after any flags are updated in
xfs_ioctl_setattr
- keeping i_mode, i_uid and i_gid uptodate in xfs_setattr
