Pull perf/urgent fixes from Arnaldo Carvalho de Melo:

- Show group details on the title line in the annotate browser
  and 'perf annotate --stdio2' output, so that the per-event
  columns can have headers (Arnaldo Carvalho de Melo)

- Fixup vertical line separating metrics from instructions and
  cleaning unused lines at the bottom, both in the annotate TUI
  browser (Arnaldo Carvalho de Melo)

- Remove duplicated 'samples' in lost samples warning in
  'perf report' (Arnaldo Carvalho de Melo)

- Synchronize i915_drm.h, silencing the perf build process,
  automagically adding support for the new DRM_I915_QUERY
  ioctl (Arnaldo Carvalho de Melo)

- Make auxtrace_queues__add_buffer() allocate struct buffer,
  from a patchkit already applied (Adrian Hunter)
