Changes:

- Made sure that C++ compilers do not complain about the header files
  include/pub_tool_libcassert.h and include/pub_tool_basics.h.
- Added the source file none/tests/valgrind_cpp_test.cpp. This source file
  is compiled together with the regression tests in order to verify that
  Valgrind's public header files compile cleanly with a C++ compiler.
These modifications are based on a patch provided by Konstantin Serebryany.
