rust: look up HgRevlogIndex_GetParents() from symbol table

And removes the unused index_get_parents_checked() function.

I expect the Index struct will be turned into a pyobject type, though I
haven't written any PoC-level patches yet.

Set up

  $ hg init repo
  $ cd repo

Try to import an empty patch

  $ hg import --no-commit - <<EOF
  > EOF
  applying patch from stdin
  abort: stdin: no diffs found
  [255]

No dirstate backups are left behind

  $ ls .hg/dirstate* | sort
  .hg/dirstate
