widening: duplicate generateellipsesbundle2() for widening

The widening and the non-widening code are quite different. It will be
clearer to have them as sepearate functions. To start with, I've just
copied it exactly, so it's clearer over the next few patches how
they're different.

The new function should gradually become more similar to
bundle2.widen_bundle(), and should perhaps eventually be merged with
that function. However, I've left it in narrowbundle2.py for now since
it still depends on constants like _KILLNODESIGNAL there.

Test template output

  $ cat tmp/c.json

Test working directory

Environment variables are not visible by default

  $ PATTERN='t4' hg log -r '.' -T "{ifcontains('PATTERN', envvars, 'yes', 'no')}\n"
  no

Environment variable visibility can be explicit

  $ PATTERN='t4' hg log -r '.' -T "{envvars % '{key} -> {value}\n'}" \
  >                 --config "experimental.exportableenviron=PATTERN"
  PATTERN -> t4

Test behavior of output when directory structure does not already exist

  $ mkdir foo
  $ echo a > foo/a
  $ hg add foo/a
  $ hg commit -qm "add foo/a"
  $ hg cat --output "output/%p" foo/a
  $ cat output/foo/a
  a
