In the memcheck monitor 'leak_search', add a "new" keyword corresponding to the delta leak search mode LCD_New. Add a new client request VALGRIND_DO_NEW_LEAK_CHECK. When doing a delta leak search, new loss records are marked with "new" (whatever the delta leak search mode). Note that trailing white spaces were removed in mc_main.c. A much small diff can be looked at by using the -w diff option.
