unbundle: faster computation of changed heads

To compute the set of changed heads it's sufficient to look at the recent commits,
instead of looking at all heads currently in existence.

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 tip "C"

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

Abort doesn't lose the commits that were already in the right place

  $ hg init abort
  $ cd abort
  $ hg debugdrawdag <<EOF
  > C
  > |
  > B D  # B/file = B
  > |/   # D/file = D
  > A
  > EOF
  $ hg rebase -r C+D -d B
  rebasing 2:ef8c0fe0897b D "D"
  merging file
  warning: conflicts while merging file! (edit, then use 'hg resolve --mark')
  unresolved conflicts (see 'hg resolve', then 'hg rebase --continue')
  [240]
  $ hg rebase --abort
  rebase aborted
  $ hg tglog

  $ cd ..

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
  > D
  > |
  > C
  > |
  > B
  > |
  > A
  > EOF
