 - Issue #22115: Added methods trace_add, trace_remove and trace_info in the

   trace_vdelete and trace_vinfo that use obsolete Tcl commands and might

+  not work in future versions of Tcl.  Fixed old tracing methods:
+  trace_vdelete() with wrong mode no longer break tracing, trace_vinfo() now
+  always returns a list of pairs of strings, tracing in the "u" mode now works.
