Subject: [PATCHv3 0/6] perf, tool: Allow to use hw events in PMU syntax

hi,
here's the change to make following syntax available:
  perf stat -e cpu/event=instructions/u ls

this is identical to:
  perf stat -e instructions:u ls

v3 changes:
  - patches v2 1,5,6,9 are already in
  - patch 1 - sysfs 'events' attribute file names with dashes '-'
            - using 'event/umask/inv/cmask' terms assigments instead simple 'config'
  - patch 2 - undefined events sysfs attributes filtered out

v2 changes:
  - making the hw events translations available under the 'events',
    the userspace trnaslation is then done by existing term aliasing
    code with some little tweeks ;)
  - patches 1-3 are independent fixies

Attached patches:
  1/6 perf, x86: Making hardware events translations available in sysfs
  2/6 perf, x86: Filter out undefined events from sysfs events attribute
  3/6 perf, tool: Fix pmu object alias initialization
  4/6 perf, tool: Properly free format data
  5/6 perf, tool: Add support to specify hw event as pmu event term
  6/6 perf, test: Add automated tests for pmu sysfs translated events
