Progress indication mechanism is refactored to support incrementing progress within multithreaded algorithms. The class Message_ProgressIndicator is only an interface to the user application. It accumulates the progress provided by progress scopes. The counter is protected by mutex for thread-safety. The new class Message_ProgressScope replacing Message_ProgressSentry should be used to advance the progress. The scopes are nested to each other to reflect the nested nature of operations. The new class Message_ProgressRange should be used to pass the progress to sub-scopes. All OCCT algorithms involving progress indication have been updated to new API. Improvements in Draw_ProgressIndicator: - Separate console mode has been added in order to make possible to put the progress into std::cout instead or in addition to the draw interpreter, instead of trigger option "-tclOutput". - Treatment of Ctrl-Break signal has been added. Now any operation can be aborted by Ctrl-C or Ctrl-Break keystroke. Added new test case 'perf fclasses progr_par' for testing of parallel work of the progress.
