This patch modifies the behaviour of the MPC8xx/8xxx watchdog. On the MPC8xx,
at 133Mhz, the maximum timeout of the watchdog timer is 1s, which means it must
be pinged twice a second. This is not in line with the Linux watchdog concept
which is based on a default watchdog timeout around 60s.

Occassionally events (e.g., context-switch, sched tracepoints) are losing
the conversion of sample data associated with a thread. For example:
$ perf record -e sched:sched_switch -c 1 -a -- sleep 5
$ perf script
ls 30482 [000] 1379727.583037: sched:sched_switch: prev_comm=ls
prev_pid=30482 .
Avoid walking the list of idle symbols more than once by setting a
flag in the symbol struct.

The PERF_RECORD_FORK event is already collected as part of the use of
cmd_record and those events are analyzed as part of the libperf machinery.
Using the fork tracepoint as well just duplicates the event load.

Not used in the function, so no sense in doing the lookup here. Thread look
up will be done in the timehist command, and no sense in doing it twice.

Leverage new exclude symbol list to allow user to not see certain functions
in a backtrace. For example repeating patterns like:

Event is not needed nor analyzed. Since perf-sched leverages perf-record
to capture the sched data, we already capture task events like EXIT.

Context switch events are 64 bytes; sched_switch events are 136 bytes.
Both indicate scheduling changes, so allow user to leverage the smaller

By default 'perf sched timehist' dumps a run-time summary for each task. The
summary includes the number of times the process was scheduled and the min, max
and average run times when scheduled (ie., a measure of how CPU time the task
wanted). Summary of idle times per cpu is also shown.

Any event can have RAW data attribute set. The intent of the function is
to determine if the session has tracepoints, so check for the type of each
