ExternalData: Preserve escaped semicolons during argument expansion The CMake language implicitly flattens lists so a ";" in a list element must be escaped with a backslash. List expansion removes backslashes escaping semicolons to leave raw semicolons in the values. Teach ExternalData_Add_Test and ExternalData_Expand_Arguments to re-escape semicolons found in list elements so the resulting argument lists work as if constructed directly by the set() command. For example: ExternalData_Add_Test(Data NAME test1 COMMAND ... "a\\;b") ExternalData_Expand_Arguments(Data args2 "c\\;d") add_test(NAME test2 COMMAND ... ${args2}) should be equivalent to set(args1 "a\\;b") add_test(NAME test1 COMMAND ... ${args1}) set(args2 "c\\;d") add_test(NAME test2 COMMAND ... ${args2}) which is equivalent to add_test(NAME test1 COMMAND ... "a;b") add_test(NAME test2 COMMAND ... "c;d") Note that it is not possible to make ExternalData_Add_Test act exactly like add_test when quoted arguments contain semicolons because the CMake language flattens lists when constructing function ARGN values. This re-escape approach at least allows test arguments to have semicolons. While at it, teach ExternalData APIs to not transform "DATA{...;...}" arguments because the contained semicolons are non-sensical.

Add ExternalData module Take files we previously distributed in ITK 4.3.1: CMake/ExternalData.cmake CMake/ExternalData_config.cmake.in and add them for distribution in upstream CMake. Update the copyright notice block format to follow CMake conventions.
