    Description

      The changes I am introducing for WT-5478 do not use a cursor in the standard way. I am using the history store cursor to create the key and value in the ITEM forms, but then I am doing an internal row search and inserting manually created update chain on the history store page.

      We could encapsulate that functionality in a new history store cursor type. The usage of the history store cursor will then appear the same as any other cursor and the insertion/deletion by directly putting updated on the page will be abstracted out.
