[PATCHv10 0/7] Expose submodule parallelism to the user

This replaces origin/sb/submodule-parallel-update
and is based on origin/master

* broke out the patch for redirecting errors to stderr in "submodule update"
  (Thanks Jonathan, Jacob)
* use git_config_int and manually check for less than 0.
  (Thanks Junio)
* use an enum consistently now for submodule update strategy
  (Thanks Junio)
* fixed the funny indentation

I haven't looked at how this integrates with Davids refs backend, I'll take a
look at the merge tomorrow

Sorry for the long turn around time,
Thanks,
Stefan

  fetching submodules: respect `submodule.fetchJobs` config option
  submodule update: direct error message to stderr
  git submodule update: have a dedicated helper for cloning
  submodule update: expose parallelism to the user
  clone: allow an explicit argument for parallel submodule clones
