config_entries: abstract away retrieval of config entries The code accessing config entries in the `git_config_entries` structure is still much too intimate with implementation details, directly accessing the maps and handling indices. Provide two new functions to get config entries from the internal map structure to decouple the interfaces and use them in the config file code. The function `git_config_entries_get` will simply look up the entry by name and, in the case of a multi-value, return the last occurrence of that entry. The second function, `git_config_entries_get_unique`, will only return an entry if it is unique and not included via another configuration file. This one is required to properly implement write operations for single entries, as we refuse to write to or delete a single entry if it is not clear which one was meant.
