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.
