/* The hell below need some explanations. For each symbolic number, we need to define it with
 * TRACE_DEFINE_ENUM() and in a list for __print_symbolic.
 *
 *   1. Define a new macro that call TRACE_DEFINE_ENUM():
 *
 *          #define xxx_name(sym) TRACE_DEFINE_ENUM(sym);
 *
 *   2. Define list of all symbols:
 *
 *          #define list_names     \
 *             ...                 \
 *             xxx_name(XXX)       \
 *             ...
 *
 *   3. Instantiate that list_names:
 *
 *          list_names
 *
 *   4. Redefine xxx_name() as an entry of array for __print_symbolic()
 *
 *          #undef xxx_name
 *          #define xxx_name(msg) { msg, #msg },
 *
 *   5. list_name can now nearly be used with __print_symbolic() but, __print_symbolic() dislike
 *      last comma of list. So we define a new list with a dummy element:
 *
 *          #define list_for_print_symbolic list_names { -1, NULL }
