repo: rework parser setup to handle `init -c`

We added support for `repo init -c` to main.py, but not to the
launcher, so the -c option only works after the first init has
run which kind of defeats its purpose.  Rework the parser setup
so that we can tell it whether it's for "init" or "gitc-init"
and then add the -c option in the same way we do in main.py.

This has the benefit of getting the parser entirely out of the
module scope which makes it a lot easier to reason about, and
it means we can write some unittests.

repo

Repo is a tool built on top of Git. Repo helps manage many Git repositories, does the uploads to revision control systems, and automates parts of the development workflow. Repo is not meant to replace Git, only to make it easier to work with Git. The repo command is an executable Python script that you can put anywhere in your path.

Install

Many distros include repo, so you might be able to install from there.

# Debian/Ubuntu.
$ sudo apt-get install repo

# Gentoo.
$ sudo emerge dev-vcs/repo

You can install it manually as well as it's a single script.

$ mkdir -p ~/.bin
$ PATH="${HOME}/.bin:${PATH}"
$ curl https://storage.googleapis.com/git-repo-downloads/repo > ~/.bin/repo
$ chmod a+rx ~/.bin/repo
