Upstream for mcrypt is effectively dead so incorporate patches from
other OSS packaging systems. These patches address the following:
* CVE-2012-4409 (fix)
* CVE-2012-4527 (fix)
* Spelling and grammar fixes for man page
* Fix potential format-string attacks (no vulnerability Id)
* Fix potential buffer overflows (no vulnerability Id)
* Make native format default as in Debian, Red Hat, and SUSE since
openpgp format handling is seriously broken.
* Fix ARM build [unclear if this is necessary for non-Linux systems]
* Correct include file for OSX
