Fixed swift mailing lists links

- This commit is part of the work to clean up all our broken links in
  apple#369. This can be shipped on it's own, so I'm separating it out to
  keep the main PR as small as possible.
- This commit replaces links to `https://lists.swift.org/mailman/listinfo`
  with `https://lists.swift.org/pipermail/`
- In cases where we guide users to submit feedback, I've also added a `>
  Note` that explains that mailing lists are now closed and archived,
  and they should use forums instead.

 It is a strong goal that the vast majority of sources that built with the Swift 3.0 compiler continue to build with the Swift 3.1 compiler. The exception will be bug fixes to the compiler that cause it to reject code that should never have been accepted in the first place. These cases should be relatively rare in practice.
