[PATCH] tracing: Fix typo in comments, print info and function

[Cai Huoqing <caihuoqing@baidu.com>]

Fix typo:
*singe  ==> single
*outputing  ==> outputting
*ingore  ==> ignore
*preapre  ==> prepare
*overlayed  ==> overlaid
*alloced  ==> allocated
*varaibles  ==> variables
*timestemp  ==> timestamp
*reseted  ==> reset
*overwite  ==> overwrite
