subrepos: prompt on conflicts on update with dirty subrepos

Consider a repository with a single subrepository. The changesets in
the main repository reference the subrepository changesets like this:

  m0 -> s0
  m1 -> s1
  m2 -> s2

Starting from a state (m1, s0), doing 'hg update m2' in the main
repository will yield a conflict: the subrepo is at revision s0 but
the target revision says it should be at revision s2.

Before this change, Mercurial would do (m1, s0) -> (m2, s2) and thus
ignore the conflict between the working copy and the target revision.

With this change, the user is prompted to resolve the conflict by
choosing which revision he wants. This is consistent with 'hg merge',
which also prompts the user when it detects conflicts in the merged
.hgsubstate files.

The prompt looks like this:

  $ hg update tip
   subrepository sources for my-subrepo differ
  use (l)ocal source (fc627a69481f) or (r)emote source (12a213df6fa9)?

  $ "$TESTDIR/hghave" svn svn-bindings || exit 80

  $ fixpath()
  > {
  >     tr '\\' /
  > }
  $ cat > $HGRCPATH <<EOF
  > [extensions]
  > convert = 
  > graphlog =
  > EOF

  $ svnadmin create svn-repo
  $ svnpath=`pwd | fixpath`


  $ expr "$svnpath" : "\/" > /dev/null
  > if [ $? -ne 0 ]; then
  >   svnpath="/$svnpath"
  > fi
  > svnurl="file://$svnpath/svn-repo"

Now test that it works with trunk/tags layout, but no branches yet.

Initial svn import

  $ mkdir projB
  $ cd projB
  $ mkdir trunk
  $ mkdir tags
  $ cd ..

  $ svnurl="file://$svnpath/svn-repo/proj%20B"
  $ svn import -m "init projB" projB "$svnurl" | fixpath
  Adding         projB/trunk
  Adding         projB/tags
  
  Committed revision 1.

Update svn repository

  $ svn co "$svnurl"/trunk B | fixpath
  Checked out revision 1.
  $ cd B
  $ echo hello > 'letter .txt'
  $ svn add 'letter .txt'
  A         letter .txt
  $ svn ci -m hello
  Adding         letter .txt
  Transmitting file data .
  Committed revision 2.

  $ "$TESTDIR/svn-safe-append.py" world 'letter .txt'
  $ svn ci -m world
  Sending        letter .txt
  Transmitting file data .
  Committed revision 3.

  $ svn copy -m "tag v0.1" "$svnurl"/trunk "$svnurl"/tags/v0.1
  
  Committed revision 4.

  $ "$TESTDIR/svn-safe-append.py" 'nice day today!' 'letter .txt'
  $ svn ci -m "nice day"
  Sending        letter .txt
  Transmitting file data .
  Committed revision 5.
  $ cd ..

Update svn repository again

  $ cd B

  $ echo "nice to meet you" > letter2.txt
  $ svn add letter2.txt
  A         letter2.txt
  $ svn ci -m "second letter"
  Sending        letter .txt
  Adding         letter2.txt
  Transmitting file data ..
  Committed revision 6.

  $ svn copy -m "tag v0.2" "$svnurl"/trunk "$svnurl"/tags/v0.2
  
  Committed revision 7.

  $ "$TESTDIR/svn-safe-append.py" "blah-blah-blah" letter2.txt

Check convert_revision extra-records.
This is also the only place testing more than one extra field in a revision.

  $ cd stoprev
  $ hg tip --debug | grep extra
  extra:       branch=default
  extra:       convert_revision=svn:........-....-....-....-............/proj B/trunk@1 (re)
