Keep calm: remember that the standard library has many more public exports than the average target, and that this contains ALL of them at once. I also deliberately tried to tag nearly every top-level decl, even if that was just to explicitly mark things @internal, to make sure I didn't miss something. This does export more than we might want to, mostly for protocol conformance reasons, along with our simple-but-limiting typealias rule. I tried to also mark things private where possible, but it's really going to be up to the standard library owners to get this right. This is also only validated against top-level access control; I haven't fully tested against member-level access control yet, and none of our semantic restrictions are in place. Along the way I also noticed bits of stdlib cruft; to keep this patch understandable, I didn't change any of them. Swift SVN r19145
