include/cppunit/Portability.h: moved OStringStream alias definition to
Portability/Stream.h. User need to define EVC4 to indicate that
config-evc4.h should be used. (how to we detect this automatically ?).
Notes that this means it might be needed to add #include <string> to some
headers since its no longer included by Portability.h.

* include/cppunit/Portability/Stream.h: define alias OStringStream, stdCOut(),
and OFileStream. If CPPUNIT_NO_STREAM is defined (evc4 config), then provides
our own implementation (based on sprintf and fwrite).

* include/cppunit/config/config-evc4.h: config file for embedded visual c++ 4.
Still need to detect for this platform in Portability.h (currently relying on
EVC4 being defined...)

* *.[cpp/h]: most source files have been impacted with the following change:
#include <iostream> -> #include <cppunit/Portability/Stream.h>
std::ostream -> CPPUNIT_NS::OStream
std::ofstream -> CPPUNIT_NS::OFileStream
std::cout -> CPPUNIT_NS::stdCOut()
std::endl -> "\n"
Also, code using std::cin as been defined out if CPPUNIT_NO_STREAM was defined.
The exact list of impact files can be obtain in CVS using tags:
TG_CPPUNIT_NO_STREAM_BEFORE & TG_CPPUNIT_NO_STREAM_AFTER.

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.

* src/cppunit/TestFactoryRegistry.cpp: use CppUnitMap instead of std::map.

* src/DllPlugInTester/CommandLineParser.h: use CppUnitDeque instead
std::deque.

* examples/cppunittest/*.h:
* examples/cppunittest/*.cpp: removed all usage of CppUnitTest namespace.
Everything is now in global space.

* examples/*/*.h:
* examples/*/*.cpp: replaced usage of CppUnit:: with CPPUNIT_NS::.

* examples/ClockerPlugIn/ClockerModel.h: use CppUnit STL wrapper instead
of STL container.

src/DllPlugInTester/makefile.am: removed ld.so from LDADD flags.

* src/DllPlugInTester/CommandLineParser.h:
* src/DllPlugInTester/CommandLineParser.cpp: rewrote, fixed problem
with double quotes in command line...

* src/DllPlugInTester/CommandLineParserTest.h:
* src/DllPlugInTester/CommandLineParserTest.cpp:
* src/DllPlugInTester/DllPlugInTesterTest.cpp: added, unit tests for
CommandLineParser.

* src/msvc6/TestPlugIn/*: removed.
