Add `eprint!` and `eprintln!` macros to the prelude. These are exactly the same as `print!` and `println!` except that they write to stderr instead of stdout. Issues rust-lang#39228 and rust-lang#40528; previous PR rust-lang#39229; accepted RFC rust-lang/rfcs#1869; proposed revision to The Book rust-lang/book#615. I have _not_ revised this any since the original submission; I will do that later this week. I wanted to get this PR in place since it's been quite a while since the RFC was merged. Known outstanding review comments: * [x] @steveklabnik requested a new chapter for the unstable version of The Book -- please see if the proposed revisions to the second edition cover it. * [x] @nodakai asked if it were possible to merge the internal methods `_print` and `_eprint` - not completely, since they both refer to different internal globals which we don't want to expose, but I will see if some duplication can be factored out. Please let me know if I missed anything.

Here are draft changes to the second edition for
eprintln!. This unfortunately touches a number of chapters that are close to being finalized, but I think it's important to mention this early on.I forked for this quite a while ago, apologies for the potentially messy merge.
