We adopt Debian's patch for CVE-2012-6702 and CVE-2016-5300 (already
sent for review for the master branch).

We also adapt the CVE-2015-1283 "re-fix" patch to apply to upstream's
fix for CVE-2015-1283. The Debian "re-fix" patch had some context
(comments) that did not exist in the upstream 2.1.1 release.

And as before, we patch for CVE-2016-0718.

It's not possible for me test this on core-updates (too much to build).
On master, I made a new expat-2.1.1 package that inherited from expat
and built that with the patches.

The merge will probably be messy...

Off-topic: A regular package and a grafted package on master, and an
updated version of the package on core-updates... this is getting very
complicated and we should try our best to avoid such tangled situations
in the future.
