commit: add amend mode for commit -i

When I moved crecord into core, I didn't include the toggleAmend function (to
switch from commit to amend mode). I did it because it would have made it more
difficult to use record and crecord interchangably. This patch reintroduces the
amend mode for commit -i as well as two tests to verify the behavior of the
function.

Set up a repo

  $ cat <<EOF >> $HGRCPATH
  > [ui]
  > interactive = true
  > [experimental]
  > crecord = true
  > crecordtest = testModeCommands
  > EOF

  $ hg init a
  $ cd a

Committing only one hunk while aborting edition of hunk

- Untoggle all the hunks, go down to the second file
- unfold it
- go down to second hunk (1 for the first hunk, 1 for the first hunkline, 1 for the second hunk, 1 for the second hunklike)
- toggle the second hunk
- toggle on and off the amend mode (to check that it toggles off)
- edit the hunk and quit the editor immediately with non-zero status
- commit
