      Description

      Currently each INodeDirectorySection.Entry contains variable numbers of INodeReference entries. The INodeReference entries are inlined, therefore it is difficult to quickly navigate through a INodeDirectorySection.Entry. Skipping through a INodeDirectorySection.Entry without parsing is essential to parse these entries in parallel.

      This jira proposes to consolidate INodeReferences into a section and give each of them an ID. The INodeDirectorySection.Entry can store the list of the IDs as a repeated field. That way we can leverage the existing code in protobuf to quickly skip through a INodeDirectorySection.Entry.
