Subject: [PATCH 12/12] perf script: Add --show-all-events option

Adding --show-all-events option to show all
side-bad events with single option, like:

  $ perf script --show-all-events
  swapper     0 [000]     0.000000: PERF_RECORD_MMAP -1/0: [0xffffffffa6000000(0xc00e41) @ 0xffffffffa6000000]: x [kernel.kallsyms]_text
  ...
  swapper     0 [000]     0.000000: PERF_RECORD_KSYMBOL addr ffffffffc01bc362 len 229 type 1 flags 0x0 name bpf_prog_7be49e3934a125ba
  swapper     0 [000]     0.000000: PERF_RECORD_BPF_EVENT type 1, flags 0, id 29
  ...
  swapper     0 [000]     0.000000: PERF_RECORD_FORK(1:1):(0:0)
  systemd     0 [000]     0.000000: PERF_RECORD_COMM: systemd:1/1
  ...
  swapper     0 [000] 63587.039518:          1 cycles:  ffffffffa60698b4 [unknown] ([kernel.kallsyms])
  swapper     0 [000] 63587.039522:          1 cycles:  ffffffffa60698b4 [unknown] ([kernel.kallsyms])
