config: add --expiry-date
Add --expiry-date as a data-type for config files when 'git config --get' is used. This will return any relative or fixed dates from config files as timestamps. This is useful for scripts (e.g. gc.reflogexpire) that work with timestamps so that '2.weeks' can be converted to a format acceptable by those scripts/functions. Following the convention of git_config_pathname(), move the helper function required for this feature from builtin/reflog.c to builtin/config.c where other similar functions exist (e.g. for --bool or --path), and match the order of parameters with other functions (i.e. output pointer as first parameter).
