When accumulating callchain entry, also save current snapshot of the
chain so that it can show the rest of the chain.

Add report.children config option for setting default value of
callchain accumulation. It affects the report output only if
perf.data contains callchain info.
A user can write .perfconfig file like below to enable accumulation
by default:
$ cat ~/.perfconfig

children = true
And i
Call __hists__add_entry() for each callchain node to get an
accumulated stat for an entry. Introduce new cumulative_iter ops to
process them properly.

Now perf top and perf report will show children column by default if
it has callchain information.

Hello,
This is a new attempt to implement cumulative hist period report.
This work begins from Arun's SORT_INCLUSIVE patch [1] but I completely
rewrote it from scratch.
In this version, I separated out the --percentage patchset not to have
dependency on it since it requires further works.
Please
Maintain accumulated stat information in hist_entry->stat_acc if
symbol_conf.cumulate_callchain is set. Fields in ->stat_acc have same
vaules initially, and will be updated as callchain is processed later.

There're some duplicate code when adding hist entries. They are
different in that some have branch info or mem info but generally do
same thing. So introduce new struct hist_entry_iter and add callbacks
to customize each case in general way.
The new perf_evsel__add_entry() function will look lik
If -g cumulative option is given, it needs to show entries which don't
have self overhead. So apply percent-limit to accumulated overhead
percentage in this case.

The cpumode and level in struct addr_localtion was set for a sample

Update it accordingly based on the fact whether the map is a part of
the kernel or not. This is a reverse of wh

The --children option is for showing accumulated overhead (period)
value as well as self overhead. It should be used with one of -g or
--call-graph option.

It is possble that a callchain has cycles or recursive calls. In that
case it'll end up having entries more than 100% overhead in the
output. In order to prevent such entries, cache each callchain node
and skip if same entry already cumulated.
