Add support for recording and displaying the transaction flags.
They are essentially a new sort key. Also display them
in a nice way to the user.

The ip_event struct assumes fixed positions for ip, pid and tid.  That
is no longer true with the addition of PERF_SAMPLE_IDENTIFIER.  The
information is anyway in struct sample, so use that instead.

Add a new parameter for 'pid' to machine__findnew_thread().
Change callers to pass 'pid' when it is known.

Note that callers sometimes want to find the main thread
which has the memory maps.  The main thread has tid == pid
so the usage in that case is:

	machine__findnew_thread(machine, pid, pid)

whereas the usage to find the specific thread is:

	machine__findnew_thread(machine, pid, tid)

to pass it to perf_event__preprocess_sample().  So remove it.

perf record has a new option -W that enables weightened sampling.

Add sorting support in top/report for the average weight per sample and the
total weight sum. This allows to both compare relative cost per event
and the total cost over the measurement period.

Add the necessary glue to perf report, record and the library.

v2: Merge with new hist refactoring.
v3: Fix manpage. Remove value check.
Rename global_weight to weight and weight to local_weight.
v4: Readd sort keys to manpage
v5: Move weight to end
v6: Move weight to template
v7: Rename weight key.

Original patch from Andi modified by Stephane Eranian <eranian@google.com>
to include ONLY the weight supporting code and apply to pristine 3.8.0-rc4.

Currently the setup_sorting() is called for parsing sort keys and exits
if it failed to add the sort key.  As it's included in libperf it'd be
better returning an error code rather than exiting application inside of
the library.

That consolidates the grouping of host + guests, isolating a bit more of
functionality now centered on 'perf_session' that can be used
independently in tools that don't need a 'perf_session' instance, but
needs to have all the thread/map/symbol machinery.

As they are used from diff and event group report, add a test case to
verify their behaviors.

In this test I made a fake machine and two evsel.  Each evsel got 10
samples (so hist entries) - 5 are common and the rests are not.  So
after hists__match() both of them will have 5 entries with pair set.

And the second evsel has a collapsed entry so that the total number is 9
- I made it in order to simulate more realistic case.  Thus after
hists__link the first entry will have 14 entries - 5 are common (w/
pair), 5 are unmatch (w/o pair) and 4 are dummy (w/ pair).  And the
second entry will have 9 entries all have its pair.
