Skynet是一个在线游戏框架，为了节省内存占用使用了共享proto的lua vm。这个工具利用systemtap抓取lua栈，分析函数代码的热路径。可以根据skynet里的服务id来单独看一个服务的lua栈。

Usage

#change the skynet bin source to your path, and add -g to 3rd/lua Makefile in skynet project
sudo ./monitor_skynet_and_gen_svg.sh skynet_pid skynet_bin_path serviceid_in_decimal

Then use dump_lua_function to convert filename:lineno to filename:func.
