This moves the getColorDepth function to the new internal/tty file. This is important to properly give attributions to @sindresorhus.

I also improved the detection by adding new values that should be checked. I am currently playing around with ncurses has_colors function. It does seem to work fine, I am just not sure where I should expose the function and how this should work on e.g. Windows. Somewhat similar: tput colors. Adding that would allow to detect simple color support. A couple of the terminals that support colors actually support more colors than currently returned, but I did not yet find a good way to always detect the version (as I have to install the terminal etc...). If anyone has a idea how to detect color support without checking environment variables: please let me know. printf and read can be used in combination, I am just not sure how to make use of that information for Node.js.

This definitely needs a backport to 9.x.

Seems fine to me, if @sindresorhus is okay with it too.

Also, fyi: http://no-color.org/

@addaleax I actually know that site, I just did not come up with the idea to use the information properly. So thanks a lot 👍
