[GSoC Patch 0/7] repo: add more path keys to git repo info

[K Jayatheerth <jayatheerthkulkarni2005@gmail.com>]

Series adds keys to git repo info.
Keys output paths of repository components:
* path.toplevel: repository tree.
* path.superproject-working-tree: superproject tree from submodules.
* path.objects: repository objects.
* path.hooks: repository hooks.
* path.index: repository index.
* path.grafts: repository grafts.
* path.git-prefix: prefix offset.

Keys support suffixes for format.
Commits contain documentation and tests.
