D1772: tests: port revlog index code to modern API

[indygreg (Gregory Szorc)]

indygreg created this revision.
Herald added a subscriber: mercurial-devel.
Herald added a reviewer: hg-reviewers.

REVISION SUMMARY
  All revlog index parsers are now using our new type to
  represent index entries. We can now undo the custom type
  comparison code we implemented to see us through the transition.
  
  In addition, the code has been ported to use named attributes
  instead of field offsets.
