[PATCH 0/7][Outreachy] stop using the_repository global variable.

[Usman Akinyemi <usmanakinyemi202@gmail.com>]

Remove `the_repository` global variable in favor of the repository
argument that gets passed in builtin commands. 

These sets of commands are commands that use only RUN_SETUP macro in "git.c".
Basically, When `-h` is passed to any of this command outside a Git repository,
the `run_builtin()` will call the `cmd_x()` function (where `x` is any
of the command from the sets of builtin commands that `the_repository` is removed
from) with `repo` set to NULL and then early in the function, `parse_options()`
or show_usage_with_options_if_asked() call will give the options help and exit,
without having to consult much of the configuration file.

As there exist some builtin commands where the `repository` variable is accessed
before options is given exit and fail, we should check if the `repository` variable
is not NULL in such scenerio.

Some, functions also uses `the_repository` global internally, so, let's
let's refactor them and pass `struct repo` as one of the argument. 

I picked some of this files based on the above explanation, how easy they are to
resolve and how easy easy to review.
