[PATCH 00/16] perf tools: BPF related update

[Wang Nan <wangnan0@huawei.com>]

This patch set is based on perf/core.

This patch set improves perf's BPF support:

 - Support filling BPF array with values
 
   Users are allowed to pass something to BPF program through command
   line without changing the program itself.

 - Support filling BPF event array with events

   BPF program can read PMU counters through BPF's perf_event_read()
   helper.

 - Support bpf_output_event() helper

   BPF program can issue perf event to perf.data.

In this patch set:

 Patch 1/16 - 2/16 are two small bugfix related to building;

 Patch 3/16 - 13/16 add array filling support. In this 11 patches:

  Patch 3/16 - 6/16 are preparation;
  Patch 7/16 - 9/16 enables perf cmdline syntax to (basic) support
                    array filling
  Patch 10/16 - 11/16 enables setting perf events to BPF event array
  Patch 12/16 - 13/16 enables setting different slots in an array
                      with different values

 Patch 14/16 - 16/16 support bpf_output_event() helper.

In most of the patches I list commands for testing them, both normal
case and error case.
