Modify struct db_variable

* ddb/db_macro.c (db_arg_variable): Make function void.
* ddb/db_macro.h (db_arg_variable): Declare void return.
* ddb/db_task_thread.c (db_set_default_thread): Make function void.
(db_get_task_thread): Make function void.
* ddb/db_variables.c (db_set_default_thread, db_get_task_thread, db_arg_variable): Declare void return.
(db_read_write_variable): Use void in initialization.
* ddb/db_variables.h (db_variable): Make third member return void.
[FCN_NULL]: Define void.
* i386/i386/db_trace.c (db_i386_reg_value): Make function void.
