Subject: [PATCH] stacktrace: introduce snprint_stack_trace for buffer output

Current stacktrace only have the function for console output.  page_owner
that will be introduced in following patch needs to print the output of
stacktrace into the buffer for our own output format so so new function,
snprint_stack_trace(), is needed.
