histedit: record histedit source (issue3681)

Have histedit record the hex of the original changeset as already done by:
- graft
- commit --amend
- rebase

My main motivation for adding this is to prevent the creation of obsolescence cycle
(see issue3681).

Note that commit created during edit are not affected yet.

Ensure hidden revision does not prevent histedit
-------------------------------------------------

create an hidden revision

  $ cat > commands.txt <<EOF
  > pick b346ab9a313d 6 c
  > drop 59d9f330561f 7 d
  > pick cacdfd884a93 8 f
  > EOF
  $ hg histedit 6 --commands commands.txt
  0 files updated, 0 files merged, 3 files removed, 0 files unresolved
  0 files updated, 0 files merged, 0 files removed, 0 files unresolved
  $ hg log --graph

  o  6:b346ab9a313d c

  o  0:cb9a9f314b8b a
  
check hidden revision are ignored (6 have hidden children 7 and 8)

  $ cat > commands.txt <<EOF
  > pick b346ab9a313d 6 c
  > pick c13eb81022ca 8 f
  > EOF
  $ hg histedit 6 --commands commands.txt

Check that histedit respect phases
=========================================

(not directly related to the test file but doesn't deserve it's own test case)
