- Old modifications were necessary for testshl2, which has simply been excluded
  from the build for now.
- Tests in basebmp, basegfx, o3tl (that are executed during build) have been
  converted from using modified CppUnit/testshl2 to using unmodified CppUnit.
- CppUnit's DllPlugInTester has problems with OOo tests on Windows, see
  #i107562#, so for now a new cppunittester from sal is used instead.
