config: add --source option to include source of value

Showing the source of each config option is quite useful and not
something the user should have to reach for the `--debug` flag for.

I updates documentation and tests, except for one place in
`test-hgrc.t` where I thought the test might have been intended to
also test that `--debug` results in `ui.quiet` etc being test.

    With --edit, start an editor on the user-level config file. With
    --global, edit the system-wide config file. With --local, edit the
    repository-level config file.

    With --debug, the source (filename and line number) is printed
    for each config item.

    See :hg:`help config` for more information about config files.
