From c09f9acd7c7a2e85472b1ee47bf26f7c89ded43e Mon Sep 17 00:00:00 2001

Subject: Distinguish Element and Linker for ilist.

Furthermore, allow for the specification of an ElementMapper. This allows a
single "Element" type to exist on multiple inline lists, and work without
having to embed the entry type.

This is a requisite change for supporting a per-Inode list of Dirents.
