cmdrewrite: a new `hg fixup` command

This new command can be used to amend specific revisions with working copy
changes.

Implementation-wise what it basically does is:

1) commit working directory changes
2) relocate the new commit onto the target commit
3) fold them into one.

After the run, the working directory parent will be the obsoleted changeset
created in step 1 and descendants of the target will become orphans.

==========================
Testing `hg fixup` command
==========================

  $ . $TESTDIR/testlib/common.sh

  $ cat >> $HGRCPATH <<EOF
  > [extensions]
  > rebase =
  > evolve =
  > [diff]
  > git = 1
  > EOF

  $ hg help fixup
  hg fixup [OPTION]... [-r] REV
  
  aliases: fix-up
  
  add working directory changes to an arbitrary revision
  
      A new changeset will be created, superseding the one specified. The new
      changeset will combine working directory changes with the changes in the
      target revision.
  
      This operation requires the working directory changes to be relocated onto
      the target revision, which might result in merge conflicts.
  
      If fixup is interrupted to manually resolve a conflict, it can be
      continued with --continue/-c, or aborted with --abort.
  
      Note that this command is fairly new and its behavior is still
      experimental. For example, the working copy will be left on a temporary,
      obsolete commit containing the fixed-up changes after the operation. This
      might change in the future.
  
      Returns 0 on success, 1 if nothing changed.
  
  options:
  
   -r --rev REV  revision to amend
   -c --continue continue an interrupted fixup
      --abort    abort an interrupted fixup
