HFS+: add custom dentry hash and comparison operations
Add custom dentry hash and comparison operations for HFS+ filesystems that are
case-insensitive and/or do automatic unicode decomposition. The new
operations reuse the existing HFS+ ASCII to unicode conversion, unicode
decomposition and case folding functionality.
