[GSoC] [PATCH 0/2] submodule--helper: introduce subcommands for sh to C conversion

[Atharva Raykar <raykar.ath@gmail.com>]

This patch series introduces the `add clone` and `add config`
subcommands in `git submodule--helper` with the goal of converting part
of the shell code in `git-submodule.sh` related to `git submodule add`
into C code.

The first patch [1/2] has already been sent to the mailing list before:
https://lore.kernel.org/git/20210604110524.84326-1-raykar.ath@gmail.com/
No changes have been made to it since then.

Because patch [2/2] depends on changes introduced in [1/2] I am sending
them together as a series.

The eventual goal is to replace all of the shell code with equivalent C
code. Subsequent patches will replace all of shell the code past the
flag parsing of `cmd_add()` into a single call to subcommand
`submodule--helper add` which will make use of the functions introduced
in these two patches.
