copies: extract method for getting non-wdir forward copies

I may add an alternative way of getting copy metadata (from changelog,
not filelog) but the chaining with the dirstate copy metadata will be
the same, so it will probably help to have this extracted. Even if
that doesn't happen, the next patch will show that we can simplify
this a bit after this refactoring, so it seems worth it regardless.

Tests rebasing with part of the rebase set already in the
destination (issue5422)

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > rebase=
  > drawdag=$TESTDIR/drawdag.py
  > 
  > [experimental]
  > evolution.createmarkers=True
  > evolution.allowunstable=True
  > 
  > [alias]
  > tglog = log -G --template "{rev}: {node|short} {desc}"
  > EOF

  $ rebasewithdag() {
  >   N=`$PYTHON -c "print($N+1)"`
  >   hg init repo$N && cd repo$N
  >   hg debugdrawdag
  >   hg rebase "$@" > _rebasetmp
  >   r=$?
  >   grep -v 'saved backup bundle' _rebasetmp
  >   [ $r -eq 0 ] && hg tglog
  >   cd ..
  >   return $r
  > }

Rebase two commits, of which one is already in the right place

  $ rebasewithdag -r C+D -d B <<EOF
  > C
  > |
  > B D
  > |/
  > A
  > EOF
  rebasing 2:b18e25de2cf5 "D" (D)
  already rebased 3:26805aba1e60 "C" (C tip)

Can collapse commits even if one is already in the right place

  $ rebasewithdag --collapse -r C+D -d B <<EOF
  > C
  > |
  > B D
  > |/
  > A
  > EOF

Rebase with "holes". The commits after the hole should end up on the parent of
the hole (B below), not on top of the destination (A).

  $ rebasewithdag -r B+D -d A <<EOF

  > C
  > |
