commit: add option to amend the working dir parent

The --amend flag can be used to amend the parent of the working directory
with a new commit that contains the changes in the parent in addition to
those currently reported by "hg status", if there are any. The old commit
is stored in a backup bundle in ".hg/strip-backup"(see "hg help bundle"
and "hg help unbundle" on how to restore it).

Message, user and date are taken from the amended commit unless specified.
When a message isn't specified on the command line, the editor will open
with the message of the amended commit.

It is not possible to amend public changesets (see "hg help phases") or
changesets that have children.

Behind the scenes, first commit the update (if there is one) as a regular
child of the current parent. Then create a new commit on the parent's
parent with the updated contents. Then change the working copy parent
to this new combined changeset. Finally, strip the amended commit and
update commit created in the beginning.

An alternative (cleaner?) approach of doing this is suggested here:
http://selenic.com/pipermail/mercurial-devel/2012-March/038540.html

It is currently not possible to amend merge commits or recursively,
this can be added at a later time.

  $ hg init
  $ echo a > a
  $ hg add a
  $ hg commit -m "1"
  $ hg status
  $ hg copy a b
  $ hg --config ui.portablefilenames=abort copy a con.xml
  abort: filename contains 'con', which is reserved on Windows: 'con.xml'
  [255]
  $ hg status

  $ hg sum

  $ hg --debug commit -m "2"

  committed changeset 1:93580a2c28a50a56f63526fb305067e6fbf739c4

we should see two history entries

  $ hg history -v
  changeset:   1:93580a2c28a5
  tag:         tip

we should see one log entry for a

  $ hg log a
  changeset:   0:c19d34741b0a
  user:        test
  date:        Thu Jan 01 00:00:00 1970 +0000
  summary:     1
  

this should show a revision linked to changeset 0

  $ hg debugindex a
     rev    offset  length   base linkrev nodeid       p1           p2
       0         0       3      0       0 b789fdd96dc2 000000000000 000000000000

we should see one log entry for b

  $ hg log b
  changeset:   1:93580a2c28a5
  tag:         tip
  user:        test
  date:        Thu Jan 01 00:00:00 1970 +0000

this should show a revision linked to changeset 1

  $ hg debugindex b

this should show the rename information in the metadata

  $ hg debugdata b 0 | head -3 | tail -2
