[PATCHv5 0/9] Expose submodule parallelism to the user

[Stefan Beller <sbeller@google.com>]

This is also available at github/stefanbeller/git submodule-parallel-update
It applies on top of a merge of sb/submodule-parallel-fetch
(including the "run-command: detect finished children by closed pipe rather than waitpid"
sent yesterday) with
"Merge branch 'rs/daemon-plug-child-leak' into sb/submodule-parallel-update"
(d075d2604c0f9204)

The diff to v4 is below, just a change in braces.

My main motivation for resending this patch series is have it available to
reviewers of the series I am going to send next, which builds on top of this
series.

Thanks,
Stefan

Stefan Beller (9):
  run_processes_parallel: delimit intermixed task output
  submodule-config: keep update strategy around
  submodule-config: drop check against NULL
  submodule-config: remove name_and_item_from_var
  submodule-config: introduce parse_generic_submodule_config
  fetching submodules: respect `submodule.fetchJobs` config option
  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
