config: add '--show-origin' option to print the origin of a config value
If config values are queried using 'git config' (e.g. via --get, --get-all, --get-regexp, or --list flag) then it is sometimes hard to find the configuration file where the values were defined. Teach 'git config' the '--show-origin' option to print the source configuration file for every printed value.
