narrow: don't resurrect old commits when narrowing (don't strip obsmarkers)

If you have an old obsolescence-chain of commits that has been pruned
and you narrow your repo so that some of those commits get stripped
(because they affected the removed paths), then we would currently
resurrect the commit that came before (along the obsmarker chain) the
last stripped commit. That happens by the usual rules for
obsmarker-stripping. However, it's quite surprising when it happens
when you narrow your repo. This patch makes narrowing not strip
obsmarkers.

Make a narrow clone then archive it
  $ . "$TESTDIR/narrow-library.sh"

  $ hg init master
  $ cd master

  $ for x in `$TESTDIR/seq.py 3`; do
  >   echo $x > "f$x"
  >   hg add "f$x"
  >   hg commit -m "Add $x"
  > done
  $ cat >> .hg/hgrc << EOF
  > [narrowhgacl]
  > default.includes=f1 f2
  > EOF
  $ hg serve -a localhost -p $HGPORT1 -d --pid-file=hg.pid
  $ cat hg.pid >> "$DAEMON_PIDS"

  $ cd ..
  $ hg clone http://localhost:$HGPORT1 narrowclone1
  requesting all changes

  adding manifests
  adding file changes
  added 3 changesets with 2 changes to 2 files
  new changesets * (glob)
  updating to branch default
  2 files updated, 0 files merged, 0 files removed, 0 files unresolved

The clone directory should only contain f1 and f2
  $ ls -1 narrowclone1 | sort
  f1
  f2

Requirements should contain narrowhg
  $ cat narrowclone1/.hg/requires | grep narrowhg
  narrowhg-experimental

NarrowHG should track f1 and f2
  $ hg -R narrowclone1 tracked
  I path:f1
  I path:f2
