lib/trace: add trace_record tool
trace_record is used to poll the spdk trace shm file
and store new entries from it to another specified trace file.
This could help retain the trace_entires from the overlay of
trace circular buffer
Note:
* trace_record reads the input tracefile into a process-local
memory and writes trace entries to the output file only at shutdown.
* trace_record can be shut down on SIGINT or SIGTERM signal.
A usage sample is:
./spdk_trace_record -s bdev_svc -p <spdk app pid> -f trace.tmp -q
