Patch 1 to 5 clear arguments lists of many functions, remove the 'overwrite'. Because all callers of these functions doesn't need the overwrite be set, we can simply remove them from arguments lists and adjust code as if a 'false' is given. Patch 6 fix a bug that forget to setting readonly for overwrite ring buffers. Patch 7 is suggested by Liang Kan, prevent dumpping duplicated data if there's no so many events between two dumpping commands. Patch 8 is 's/backward/overwrite'. After patch 8, the concept of 'backward' is removed from most of the code, make it uniform with user interface ('--overwrite').
