rebase: enable multidest by default

This was intended to be done by D470. But there was a minor documentation
issue. The feature is quite usable now so it gets formally documented and
enabled.

There is no behavior change for people not using the `SRC` or `ALLSRC` in
rebase destination revset.

.. feature:: Rebase with different destination per source revision

  Previously, rebase only supports one unique destination. Now ``SRC`` and
  ``ALLSRC`` can be used in rebase destination revset to precisely define
  destination per each individual source revision.

  For example, the following command could move some orphaned changesets to
  reasonable new places so they become no longer orphaned::

    hg rebase
      -r 'orphan()-obsolete()'
      -d 'max((successors(max(roots(ALLSRC) & ::SRC)^)-obsolete())::)'

Binary files work but without diff hunks filtering.
(Checking w/ and w/o diff.git option.)

  >>> open('binary', 'wb').write('this\nis\na\nbinary\0')
  $ hg add binary
  $ hg ci -m 'add a binary file' --quiet

Option --follow is required.

  $ hg log -L foo,5:7
  abort: --line-range requires --follow

Non-exact pattern kinds are not allowed.

  $ cd ..
  $ hg log -f -L glob:*a*,1:2
  hg: parse error: line range pattern 'glob:*a*' must match exactly one file
  [255]

We get an error for removed files.

  $ hg rm dir/baz
  $ hg ci -m 'remove baz' --quiet
  $ hg log -f -L dir/baz,5:7 -p
  abort: cannot follow file not in parent revision: "dir/baz"
  [255]

Graph log does work yet.

  $ hg log -f -L dir/baz,5:7 --graph
  abort: graph not supported with line range patterns
