hfsplus: add metadata file's clump size calculation functionality
There are situation when HFS+ volume had been created without
AttributesFile. Such situation can take place because of using old
mkfs.hfs utility or creation HFS+ volume without taking in mind necessity
to use xattrs. For example, Mac OS X 10.4 (Tiger) doesn't create
AttributesFile during mkfs phase. Also it is a very frequent situation
for the case of users that created HFS+ volumes under Linux. As a result,
xattrs and POSIX ACLs on HFS+ volume are unavailable for such users.
This patchset implements functionality of AttributesFile creation on HFS+
volume in the case of this metadata file absence during operation of xattr
creation.
This patch:
Add functionality of metadata file's clump size calculation. Operation of
AttributesFile creation needs in clump size setting. This value will be
used when AttributesFile will be extended.
This code is adopted from code of newfs_hfs utility of diskdev_cmds packet
http://opensource.apple.com/tarballs/diskdev_cmds/.
