[PATCH v1 2/3] config: introduce repo_config_set* functions

[Glen Choo <chooglen@google.com>]

We have git_config_set() that sets a config value for the_repository's
config file, and repo_config_get* that reads config values from a struct
repository. Thus, it seems reasonable to have to have
repo_git_config_set() that can set values for a config file of a struct
repository.

Implement repo_config_set() and repo_config_set_gently(), which
take struct repository. However, unlike other instances where struct
repository is added to a repo_* function, this patch does not change the
implementations of git_config_set() or git_config_set_gently(); those
functions use the_repository much deeper in their call chain through
git_pathdup(). Mark this inconsistency as NEEDSWORK.
