Joyee Cheung 65fbc95949 src: parse --stack-trace-limit and use it in --trace-* flags
Previously, --trace-exit and --trace-sync-io doesn't take care
of --stack-trace-limit and always print a stack trace with maximum
size of 10. This patch parses --stack-trace-limit during
initialization and use the value in --trace-* flags.
