mq: backup local changes in qpush --force

qpush help says the following about --force:
1- When -f/--force is applied, all local changes in patched files will
   be lost.
2- Apply on top of local changes

In practice, qpush --force will attempt to apply the patch on top of
local changes, and on success will merge them in the pushed patch. On
failure, patched files will contain a mix of local changes (where the
patch could not apply) and a mix of patch changes (were it applied). So,
local changes are less lost than entangled with a mass of other changes.

This patch makes qpush --force backup all locally modified files touched
by the next patch being applied. When multiple patches are being pushed,
this logic is repeated for each patch. Note that modified but
successfully patched files are preserved as well.

  $ "$TESTDIR/hghave" symlink || exit 80

Source bundle was generated with the following script:

# hg init
# echo a > a
# ln -s a l
# hg ci -Ama -d'0 0'
# mkdir b
# echo a > b/a
# chmod +x b/a
# hg ci -Amb -d'1 0'

  $ hg init
  $ hg -q pull "$TESTDIR/bundles/test-manifest.hg"

The next call is expected to return nothing:

  $ hg manifest

  $ hg co
  3 files updated, 0 files merged, 0 files removed, 0 files unresolved

  $ hg manifest
  a
  b/a
  l

  $ hg manifest -v
  644   a
  755 * b/a
  644 @ l

  $ hg manifest --debug
  b789fdd96dc2f3bd229c1dd8eedf0fc60e2b68e3 644   a
  b789fdd96dc2f3bd229c1dd8eedf0fc60e2b68e3 755 * b/a
  047b75c6d7a3ef6a2243bd0e99f94f6ea6683597 644 @ l

  $ hg manifest -r 0
  a
  l

  $ hg manifest -r 1
  a
  b/a
  l

  $ hg manifest -r tip
  a
  b/a
  l

  $ hg manifest tip
  a
  b/a
  l

  $ hg manifest --all
  a
  b/a
  l

The next two calls are expected to abort:

  $ hg manifest -r 2
  abort: unknown revision '2'!
  [255]

  $ hg manifest -r tip tip
  abort: please specify just one revision
  [255]
