* generic/tclBasic.c: Added missing walk of the list of active traces

        * generic/tclTrace.c:   to cleanup references to traces being deleted.
        * generic/tclInt.h:     [Bug 1201035] Made the walk of the active trace
        * tests/trace.test (trace-34.*): list aware of the direction of trace
        scanning, so the proper correction can be made. [Bug 1224585]
