To do:
* add support for extended attribute (named fork) data stream with LIBFSHFS_ATTRIBUTE_RECORD_TYPE_EXTENTS
* check kHFSHasAttributesMask flag to see if file entry has extended attributes
* for extended attributes by name look up use native B-tree structures

* info handle implement is_empty ?

* add support for hard link count

* what about a symbolic link to HFS+ Private data directory?

* complete name case folding and decomposition tests
* on file_entry_initialize lookup com.apple.decmpfs specifically instead of all attributes?
* catalog B-tree file, include name in branch key check
* file entry API: add extents functions

* add support to print information about special files (those without a catalog record)

* classic HFS
** fshfsinfo: add support retrieving non-directory file entries using fshfsinfo -E

** API: add option to set file system encoding
** API: add means to determine if date and time values are in local time or UTC
** API: determine how to represent file mode
** add support for Mac OS codepages
