To provide the .kvi member, refactor out kvi_from_param() from the logic that caches CLI config in configsets. Now that config_context and config_context.kvi is always present when config machinery calls config callbacks, plumb "kvi" so that we can remove all calls of current_config_scope() except for trace2/*.c (which will be handled in a later commit), and remove all other current_config_*() (the functions themselves and their calls). Note that this results in .kvi containing a different, more complete set of information than the mocked up "struct config_source" in git_config_from_parameters(). Plumbing "kvi" reveals a few places where we've been doing the wrong thing: * git_config_parse_parameter() hasn't been setting config source information, so plumb "kvi" there too. * "git config --get-urlmatch --show-scope" iterates config to collect values, but then attempts to display the scope after config iteration. Fix this by copying the "kvi" value in the collection phase so that it can be read back later. This means that we can now support "git config --get-urlmatch --show-origin" (we don't allow this combination of args because of this bug), but that is left unchanged for now. * "git config --default" doesn't have config source metadata when displaying the default value. Fix this by treating the default value as if it came from the command line (e.g. like we do with "git -c" or "git config --file"), using kvi_from_param().
