If option -t is configured, a timer will be set with configured timeout when
launching acrntrace. When timer fired, acrntrace will exit.

acrntrace writes trace data to /tmp with unlimited size and will cause tmpfs
100% occupied. Consequently, some problem will raise up on SOS, like failing to
exec cmd.
This patch introduce an option -r to let user configre minimal space left on the
disk which ensures that acrntrace will exit when free storage space is less than
the reserved space. By default, we reserve 512M on the disk. Users can configure
reserved space through '-r'.

Benefits of outputing trace data as raw data:
- Smaller trace data size
- More convenient to add new trace entry. There is no need to change acrntrace
when we add new trace entry to HV. All we need do is to update the analysis
scripts to deal with this situation.
Trace data size(with 1 UOS):
~57M -- with patch
~137M -- without patch
