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

* include/cppunit/TestResult.h:
* src/cppunit/TestResult.cpp: moved documentation to header.

include/cppunit/Exception.h:
* src/cppunit/Exception.h: added setMessage().

* include/cppunit/Protector.h:
* src/cppunit/Protector.cpp: added class ProtectorGuard. Change the
reportXXX() method to support Exception passing and SourceLine.

* include/cppunit/TestCaller.h: removed 'expect exception' features.
It is now handled by ExceptionTestCaseDecorator and TestCaller no
longer need default template argument support.

* include/cppunit/TestCase.h:
* include/cppunit/extensions/TestCaller.h: runTest() is now public
instead of protected, so that it can be decorated.

* include/cppunit/TestResult.h:
* src/cppunit/TestResult.h: added pushProtector() and popProtector()
methods. This allow user to specify their own exception trap when
running test case.

* include/cppunit/extensions/TestDecorator.h:
* src/cppunit/TestDecorator.cpp: added. Extracted from TestDecorator.h.
The test passed to the constructor is now owned by the decorator.

* src/cppunit/TestCaseDecorator.cpp: added. Decorator for TestCase
setUp(), tearDown() and runTest().

TestCaseDecorator to expect that a specific exception is thrown.

change.
