perf probe: Support event name for --add option
Support event name syntax for --add option. This allows
users to specify event name for each new event.
The --add syntax is:
perf probe --add '[EVENT=]SRC:LINE ARGS'
or
perf probe --add '[EVENT=]FUNC[+OFFS|%return|:RLN][@SRC] ARGS'
e.g.
./perf probe --add myprobe1=schedule
Note: currently group name is not supported yet, because it
can cause name-space confliction with other tracepoint/
hw-breakpoint events.
