revlogdeltas: move finddeltainfo filtering inside _candidategroups

Now all "simple" filtering logic is gathered in one place. The `finddeltainfo`
method is more straightforward and the `_candidate_groups` function knows more
about filtering revisions before we compute a delta against them.

Test issue2761

  $ hg init

  $ touch to-be-deleted
  $ hg add
  adding to-be-deleted
  $ hg ci -m first
  $ echo a > to-be-deleted
  $ hg ci -m second
  $ rm to-be-deleted
  $ hg diff -r 0

Same issue, different code path

  $ hg up -C
  1 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ touch does-not-exist-in-1
  $ hg add
  adding does-not-exist-in-1
  $ hg ci -m third
  $ rm does-not-exist-in-1
  $ hg diff -r 1
