From: Atharva Raykar <raykar.ath@xxxxxxxxx> This patch completes the conversion past the flag parsing of `submodule update` by introducing a helper subcommand called `submodule--helper update`. The behaviour of `submodule update` should remain the same after this patch. We add more fields to the `struct update_data` that are required by `struct submodule_update_clone` to be able to perform a clone, when that is needed to be done. Recursing on a submodule is done by calling a subprocess that launches `submodule--helper update`, with a modified `--recursive-prefix` and `--prefix` parameter. We also introduce `update_submodules2()` and `update_submodule2()` which will supersede `update_submodules()` and `update_submodule()`. When the `--init` flag is passed to the subcommand, we do not spawn a new subprocess and call `submodule--helper init` on the submodule paths, because the Git machinery is not able to pick up the configuration changes introduced by that init call[1]. So we instead run the `init_submodule_cb()` callback over each submodule in the same process. While we are at it, we also remove the fetch_in_submodule() shell function since it is no longer used anywhere.
