tracing: add print format to event trace format files
This patch adds the internal print format used to print the raw events
to the event trace point format file.
# cat /debug/tracing/events/sched/sched_switch/format
name: sched_switch
ID: 29
format:
field:unsigned char type; offset:0; size:1;
field:unsigned char flags; offset:1; size:1;
field:unsigned char preempt_count; offset:2; size:1;
field:int pid; offset:4; size:4;
field:int tgid; offset:8; size:4;
field:pid_t prev_pid; offset:12; size:4;
field:int prev_prio; offset:16; size:4;
field special:char next_comm[TASK_COMM_LEN]; offset:20; size:16;
field:pid_t next_pid; offset:36; size:4;
field:int next_prio; offset:40; size:4;
print fmt: "prev %d:%d ==> next %s:%d:%d"
