color: introduce support for colorizing stderr
So far, we only ever asked whether stdout wants to be colorful. In the upcoming patches, we will want to make push errors more prominent, which are printed to stderr, though. So let's refactor the want_color() function into a want_color_fd() function (which expects to be called with fd == 1 or fd == 2 for stdout and stderr, respectively), and then define the macro `want_color()` to use the want_color_fd() function. And then also add a macro `want_color_stderr()`, for convenience and for documentation.
