[Buildroot] [PATCH 0/4 v2] core/download: add support for git sub-modules (branch yem/git)

[Yann E. MORIN <yann.morin.1998@free.fr>]

Hello All!

This little series adds support for packages coming from a git clone,
with git sub-modules.

The commit logs are pretty detailed, but roughly, it goes as thus;

  - we can't get sub-modules in a bare clone, so we no longer use bare
    clones, but use full clones (with a working copy);

  - git-archive does not support submodules, so we generate archives
    manually;

  - we check out the working copy to the correct cset, then we retrieve
    the submodules;

  - we expose a new package variable to request sub-modules.


Changes v1 -> v2:
  - properly accept -r in the download wrapper  (Aleksandar)
  - split the non-bare-git and manual-archive changes in two separate
    patches, as they are not semantically related
  - some of my usual typoes fixed...


Regards,
Yann E. MORIN.
