Taeung Song c6fc018a7a perf config: Add support setting variables in a config file
Add setting feature that can add config variables with their values to a
config file (i.e. user or system config file) or modify config key-value
pairs in a config file.  For the syntax examples:

    perf config [<file-option>] [section.name[=value] ...]

e.g. You can set the ui.show-headers to false with

    # perf config ui.show-headers=false

If you want to add or modify several config items, you can do like

    # perf config annotate.show_nr_jumps=false kmem.default=slab

Committer notes:

Testing it:

  $ perf config -l
  top.children=true
  report.children=false
  $
  $ perf config top.children=false
  $ perf config -l
  top.children=false
  report.children=false
  $
  $ perf config kmem.default=slab
  $ perf config -l
  top.children=false
  report.children=false
  kmem.default=slab
  $
