debugindex: move the logic into its own module

Adding more information will significantly increase the amount of code. So we
move the code into its own module before making it more complex.

Demonstrate that the linknode points to a commit that is actually in the repo
after the strip operation. Otherwise remotefilelog has to search every commit in
the repository looking for a valid linkrev every time it's queried, such as
during push.
