Leverage new exclude symbol list to allow user to not see certain functions in a backtrace. For example repeating patterns like: do_select core_sys_select sys_select can be reduced to just sys_select when dumping callchains, consuming less real estate on the screen while still conveying the essential message - the process is in a select call.
