98dcf14d7f perf tools: Add kernel AUX area sampling definitions 
Add kernel AUX area sampling definitions, which brings perf_event.h into
line with the kernel version.

New sample type PERF_SAMPLE_AUX requests a sample of the AUX area
buffer.  New perf_event_attr member 'aux_sample_size' specifies the
desired size of the sample.

Also add support for parsing samples containing AUX area data i.e.
PERF_SAMPLE_AUX.

Committer notes:

I squashed the first two patches in this series to avoid breaking
automatic bisection, i.e. after applying only the original first patch
in this series we would have:

  # perf test -v parsing
  26: Sample parsing                                        :
  --- start ---
  test child forked, pid 17018
  sample format has changed, some new PERF_SAMPLE_ bit was introduced - test needs updating
  test child finished with -1
  ---- end ----
  Sample parsing: FAILED!
  #

With the two paches combined:

  # perf test parsing
  26: Sample parsing                                        : Ok
  #

>From following commit:

  commit 4979d0c7d0 ("perf stat record: Add record command")

5ced95b237 perf tests attr: Add 1s for exclude_kernel and task base bits 
There's an event open fallback which set exclude_kernel=1 in case use
does not have enough privileges. Adding both 0|1 for this attribute,
because we don't know what value it is.

75226c577c perf tests: Fix attr tests size values to cope with machine state on interrupt ABI changes 
Following change adjusted 'struct perf_event_attr', but let
the attr test's sizes untouched:
  60e2364e60 perf: Add ability to sample machine state on interrupt

  [jolsa@krava perf]$ ./perf test attr -vv
  --- start ---
  test child forked, pid 9719
  running './tests/attr/test-stat-group1'
    'PERF_TEST_ATTR=/tmp/tmp4drvul ./perf stat -o /tmp/tmp4drvul/perf.data -e '{cycles,instructions}' kill >/dev/null 2>&1' ret 1
  expected size=96, got 104
  FAILED './tests/attr/test-stat-group1' - match failure

Adjusting test size values for attr test.

66cd3f3a6c perf tests: Fix exclude_guest|exclude_host checking for attr tests 
We have a one of the event open fallback case in __perf_evsel__open
where we zero exclude_guest|exclude_host fields.

This means there's no way for attr tests to find out what's the right
value for those fields, so we need to check for both 0 and 1. Luckily we
still have other event parsing tests for those fields.

8dfec403e3 perf tests: Removing 'optional' field

need for 'optional' field.. old version removal leftover.

45e4089bc6 perf tests: Fix attr watermark field name typo

As the type is global through the framework and tests, the typo spawned
no error.
