py2exe: add workaround to allow bundling of hgext3rd.* extensions

py2exe doesn't know how to handle namespace packages *at all*, so it treats
them like normal packages. As a result, if we try and bundle hgext3rd.evolve
in a py2exe build, it won't work if we install evolve into the virtualenv. In
order to work around this, tortoisehg installs hgext3rd.evolve etc into its
staged hg directory, since it doesn't use a virtualenv. As a workaround for us,
we'll just allow any extra packages users want bundled are part of hg during
the pseudo-install phase that py2exe uses. I'm not happy about this, but it
*works*.

As a sample of how you'd make an MSI with evolve bundled:

    import os
    import shutil
    import subprocess
    import tempfile

    def stage_evolve(version):
      """Stage evolve for inclusion in py2exe binary."""
      with tempfile.TemporaryDirectory() as temp:
        evolve = os.path.join(temp, "evolve")
        subprocess.check_call([
            "hg.exe",
            "clone",
            "https://www.mercurial-scm.org/repo/evolve/",
            "--update",
            version,
            evolve,
        ])
        dest = os.path.join('..', 'hgext3rd', 'evolve')
        if os.path.exists(dest):
            shutil.rmtree(dest)
        shutil.copytree(os.path.join(evolve, "hgext3rd", "evolve"), dest)


    def main():
      stage_evolve('tip')
      print("\0")
      print("hgext3rd")
      print("hgext3rd.evolve")
      print("hgext3rd.evolve.hack")
      print("hgext3rd.evolve.thirdparty")


    if __name__ == "__main__":
      main()

is a script you can pass to the wix/build.py as --extra-packages-script,
and the resulting .msi will have an hg binary with evolve baked in. users
will still need to enable evolve in their hgrc, so you'd probably also
want to bundle configs in your msi for an enterprise environment, but that's
already easy to do with the support for extra features and wxs files in the
wix build process.

test sparse

  $ hg init myrepo
  $ cd myrepo
  $ cat > .hg/hgrc <<EOF
  > [extensions]

  $ echo a > show
  $ echo x > hide
  $ hg ci -Aqm 'initial'

  $ hg ci -Aqm 'two'

Verify basic --include

  $ hg up -q 0
  $ hg debugsparse --include 'hide'
  $ ls
  hide

Absolute paths outside the repo should just be rejected

#if no-windows
  $ hg debugsparse --include /foo/bar
  abort: paths cannot be absolute
  [255]
  $ hg debugsparse --include '$TESTTMP/myrepo/hide'

  $ hg debugsparse --include '/root'
  abort: paths cannot be absolute

#else
TODO: See if this can be made to fail the same way as on Unix
  $ hg debugsparse --include /c/foo/bar

  [255]
  $ hg debugsparse --include '$TESTTMP/myrepo/hide'

  $ hg debugsparse --include '/c/root'
  abort: paths cannot be absolute

#endif

Paths should be treated as cwd-relative, not repo-root-relative
  $ mkdir subdir && cd subdir
  $ hg debugsparse --include path

  hide
  subdir/path
  
  $ cd ..

Verify commiting while sparse includes other files

  $ echo z > hide
  $ hg ci -Aqm 'edit hide'
  $ ls
  hide
  $ hg manifest
  hide
  show

Verify --reset brings files back

  $ hg debugsparse --reset
  $ ls
  hide
  show
  $ cat hide

  $ cat show
  a

Verify 'hg debugsparse' default output

  $ hg up -q null
  $ hg debugsparse --include 'show*'

  $ hg debugsparse
  [include]
  show*
  
Verify update only writes included files

  $ hg up -q 0
  $ ls
  show

  $ hg up -q 1
  $ ls
  show
  show2

Verify status only shows included files

  $ touch hide
  $ touch hide3
  $ echo c > show
  $ hg status
  M show

Adding an excluded file should fail

  $ hg add hide3
  abort: cannot add 'hide3' - it is outside the sparse checkout
  (include file with `hg debugsparse --include <pattern>` or use `hg add -s <file>` to include file directory while adding)
  [255]

But adding a truly excluded file shouldn't count

  $ hg add hide3 -X hide3

Verify deleting sparseness while a file has changes fails

  $ hg debugsparse --delete 'show*'
  pending changes to 'hide'
  abort: cannot change sparseness due to pending changes (delete the files or use --force to bring them back dirty)
  [255]

Verify deleting sparseness with --force brings back files

  $ hg debugsparse --delete -f 'show*'
  pending changes to 'hide'
  $ ls
  hide
  hide2
  hide3
  show
  show2
  $ hg st
  M hide
  M show
  ? hide3

Verify editing sparseness fails if pending changes

  $ hg debugsparse --include 'show*'
  pending changes to 'hide'
  abort: could not update sparseness due to pending changes
  [255]

Verify adding sparseness hides files

  $ hg debugsparse --exclude -f 'hide*'
  pending changes to 'hide'
  $ ls
  hide
  hide3
  show
  show2
  $ hg st

  $ hg up -qC .
TODO: add an option to purge to also purge files outside the sparse config?
  $ hg purge --all --config extensions.purge=
  $ ls

For now, manually remove the files
  $ rm hide hide3

Verify rebase temporarily includes excluded files

Verify aborting a rebase cleans up temporary files

  $ hg rebase --abort --config extensions.rebase=
  cleaned up 1 temporarily added file(s) from the sparse checkout
  rebase aborted
  $ rm hide.orig

  $ ls

   hide  |  2 +-

Test status on a file in a subdir

  $ mkdir -p dir1/dir2
  $ touch dir1/dir2/file
  $ hg debugsparse -I dir1/dir2
  $ hg status
