Subject: [PATCH] Refactored the -Wdev and -Wno-dev to use a generic -W parser,
which follows the GCC pattern. Included support for setting
CMAKE_ERROR_DEPRECATED and CMAKE_WARN_DEPRECATED via the deprecated warning.
Added tests for new options and updated cmake documentation and release notes
to list new options.
