Hi,

this is the second version of my patch series that aims to add
subcommands to git-config(1) in a backwards-compatible manner. 

This series is mostly a rewrite compared to v1, so I won't go into all
the details. Most importantly:

  - I have replaced several subcommands by option. For example, `git
    config get-all` is now `git config get --all` and `git config add`
    is `git config set --append`.

  - Subcommands now perform their own parsing. This makes the code a
    whole lot more easy to reason about and ensures that there are no
    backwards incompatible changes to the old modes. This comes at the
    cost of additional code though.

  - The documentation has been adapted to mention the old syntax in a
    "DEPRECATED SYNTAX" section. It also lists how to convert old style
    syntax to new style syntax.

As I expect there to be some more discussion and thus some more versions
of this series I stopped short of some things:

  - Tests exist for most of the parts, but some modes aren't yet
    properly tested. This is mostly due to incompatibilities between old
    and new style syntax which make it hard to just run the same tests
    twice with some prefixes.

  - The `--get-colorbool` option hasn't been converted yet. I _think_ we
    might be able to introduce a new `--type=colorbool` option, but I'm
    not sure I fully grasp the usecase of this command.

Thanks for all the feedback so far!

Patrick
