Subject: [PATCH] Add a separate mode to parse footnotes the same way GitHub
 does

Resolves #20

Resolves #530

This change is similar to, but a more limited change than,
 <https://github.com/raphlinus/pulldown-cmark/pull/544>. It changes
the syntax, but does not touch the generated HTML or event API.

Motivation
----------

This commit is written with usage in mdBook, rustdoc, and docs.rs
in mind.

* Having a standard to follow, or at least a public test suite in
  [cmark-gfm] [^c], makes it easier to distinguish bugs from features.
* It makes sense to commit to following GitHub's behavior specifically,
  because mdBook chapters and docs.rs README files are often viewed in
  GitHub preview windows, so any divergence will be very annoying.
* If mdBook and docs.rs are going to use this syntax, then rustdoc
  should, too.
* Having both footnote syntaxes use the same API and rendering makes it
  more feasible for rustdoc to change the syntax over an [edition].
  To introduce a syntax change in a new edition of Rust, we must make
  rustdoc warn anyone who writes code that will have its meaning change.
  To do it, run the parser twice in lockstep (with `ENABLE_FOOTNOTES`
  on one parser, and `ENABLE_GFM_FOOTNOTES` on the other), and warn if
  they diverge.
  * Alternatively, run a Crater build with this same code to check if
    this actually causes widespread breakage.
* In particular, using tree rewriting to push the footnotes to the end
  is not as useful as it sounds, since that's not enough to exactly
  copy the way GitHub renders footnotes. To do that, you also need to
  sort the footnotes by the order in which they are *referenced*, not
  the order in which they are defined. This type of tree rewriting is
  also a waste of time if you want "margin note" rendering instead of
  putting them all at the end.

    test suite into pulldown-cmark should be fine.

+[^lorem]: If heaven ever wishes to grant me a boon, it will be a total effacing of the results of a mere chance which fixed my eye on a certain stray piece of shelf-paper. It was nothing on which I would naturally have stumbled in the course of my daily round, for it was an old number of an Australian journal, the Sydney Bulletin for April 18, 1925. It had escaped even the cutting bureau which had at the time of its issuance been avidly collecting material for my uncle's research.
+
+I had largely given over my inquiries into what Professor Angell called the "Cthulhu Cult", and was visiting a learned friend in Paterson, New Jersey; the curator of a local museum and a mineralogist of note. Examining one day the reserve specimens roughly set on the storage shelves in a rear room of the museum, my eye was caught by an odd picture in one of the old papers spread beneath the stones. It was the Sydney Bulletin I have mentioned, for my friend had wide affiliations in all conceivable foreign parts; and the picture was a half-tone cut of a hideous stone image almost identical with that which Legrasse had found in the swamp.
