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 class provides easy syntax to efficiently insert blocks of data
into XML documents with proper escapes. It replaces the old
cmCTest::MakeXMLSafe and cmSystemTools::MakeXMLSafe methods which
allocated extra memory instead of directly streaming the data.
