blkparse: add support sort program by io event
Displays each program's data sorted by program name or io event, like
Queued, Read, Write and Complete. When -S is specified the -s will be ignored.
The capital letters Q,R,W,C stand for KB, then q/r/w/c stand for IO.
The N is used for sorting programs by name, same to -s.
If you want to sort programs by how many data they queued, you can use:
blkparse -i sda.blktrace. -q -S Q -o sda.parse
