graft: exit 1 on conflicts, like merge

It's more consistent, and makes it nicer to script around hg if you
don't have to ignore exit code 255, which is the error code for
basically everything in hg.

Check out of sync nodemap
=========================

First copy old data on the side.

  $ mkdir ../tmp-copies
  $ cp .hg/store/00changelog-????????????????.nd .hg/store/00changelog.n ../tmp-copies

Nodemap lagging behind
----------------------

make a new commit

  $ echo bar2 > bar
  $ hg ci -m 'bar2'
  $ NODE=`hg log -r tip -T '{node}\n'`
  $ hg log -r "$NODE" -T '{rev}\n'
  5003

If the nodemap is lagging behind, it can catch up fine

  $ hg debugnodemap --metadata
  uid: ???????????????? (glob)
  tip-rev: 5003
  tip-node: 5c049e9c4a4af159bdcd65dce1b6bf303a0da6cf

  $ hg log -r "$NODE" -T '{rev}\n'
  5003

changelog altered
-----------------

If the nodemap is not gated behind a requirements, an unaware client can alter
the repository so the revlog used to generate the nodemap is not longer
compatible with the persistent nodemap. We need to detect that.

  $ hg up "$NODE~5"
  0 files updated, 0 files merged, 2 files removed, 0 files unresolved
  $ echo bar > babar
  $ hg add babar
  $ hg ci -m 'babar'
  created new head
  $ OTHERNODE=`hg log -r tip -T '{node}\n'`
  $ hg log -r "$OTHERNODE" -T '{rev}\n'
  5004

  $ hg --config extensions.strip= strip --rev "$NODE~1" --no-backup

the nodemap should detect the changelog have been tampered with and recover.
