Brad King 91e8d35ab8 Merge branch 'curl-upstream' into update-curl 
Resolve conflicts by taking upstream side when possible and otherwise
integrating the changes from both sides.  Be carful in CMakeLists.txt
where the OPENSSL code block that we modified previously has moved, and
preserve our previous modifications in the new location.
