This converts the CMake license to a pure 3-clause OSI-approved BSD
License. We drop the previous license clause requiring modified
versions to be plainly marked. We also update the CMake copyright to
cover the full development time range.
This version of curl was added experimentally but does not address the
problem we were hoping it fixed (an occasional upload hang). Importing
a new curl can wait until the problem is fully diagnosed and addressed.
