It consists mostly of making copy constructors and assignment operators
explicit and private, and of initializing all members in initializer lists.

hidden virtual function warning.

CodingGuideLines.txt: added. CppUnit's coding guidelines for portability.

* include/cppunit/portability/CppUnitStack.h: added. wrapper for std::stack.

* include/cppunit/portability/CppUnitSet.h: added. wrapper for std::set.

* include/cppunit/ui/text/TestRunner.h: fixed namespace definition for
deprecated TestRunner.

* include/cppunit/TestAssert.h:
* src/cppunit/TestAssert.cpp: removed old deprecated functions that did
not use SourceLine. Moved assertEquals() and assertDoubleEquals() into
CppUnit namespace.
