Its not 'diff' specific and will be useful for other use cases, like
bucketizing multiple events in a single session.

We want to match more than two hists, so that we can match more than two
perf.data files and moreover, match hist_entries (buckets) in multiple
events in a group.

So the "baseline"/"leader" will instead of a ->pair pointer, use a
list_head, that will link to the pairs and hists__match use it.

Following that perf_evlist__link will link the hists in its evsel
groups.

Arnaldo reported that annotation during perf top resulted in a segfault.
It was because the env->arch was NULL and we don't set it for a live
session.  In fact, no need to look up objdump in this case since we can
use system's default (native) objdump.

captured from a different machine because of objdump.

Since the objdump tools won't be used unless annotation was requested,
checking its presence at init time doesn't make sense.

Currently various hist browser functions receive 3 arguments for
refreshing histogram but only used from a few places.  Also it's only
for perf top command so that it can be NULL for other (and probably
most) cases.  Pack them into a struct in order to reduce number of those
unused arguments.

This is a mechanical change and does not intend a functional change.

failed to work because it tried to find out cross-compiled objdump.

However objdump for x86_64 is compatible to i686 so that it doesn't need
to do it at all.  To prevent similar artifacts, normalize arch name when
comparing host and file architectures.

The test attr suite is run only if it's run under perf source directory,
or tests are found in installed path.

Otherwise tests are omitted (notification is displayed) and finished as
successful.

The idea is run perf session with kidnapping sys_perf_event_open
function. For each sys_perf_event_open call we store the perf_event_attr
data to the file to be checked later against what we expect.

You can run this by:
  $ python ./tests/attr.py -d ./tests/attr/ -p ./perf -v

v2 changes:
  - preserve errno value in the hook

As 'perf top' has no data files to run scripts against. Also add a
is_report_browser() helper function to judge whether the running browser
is for 'perf report'.
