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
  $

c7ac24178c perf config: Add '--system' and '--user' options to select which config file is used 
The '--system' option means $(sysconfdir)/perfconfig and '--user' means
$HOME/.perfconfig. If none is used, both system and user config file are
read.  E.g.:

    # perf config [<file-option>] [options]

    With an specific config file:

    # perf config --user | --system

    or both user and system config file:

    # perf config

78ce08dfbd perf annotate: Rename 'colors.code' to 'colors.jump_arrows' 
USe 'jump_arrows' config name instead of 'code' on 'colors' section.
'colors.code' config is only for jump arrows on assembly code listings
i.e.

    │     ┌──jmp    1333
    │     │  xchg   %ax,%ax
    │     │  mov    %r15,%r10
    │     └─→cmp    %r15,%r14

But this config name seems unfit.

 'jump_arrows' is more descriptive than 'code'.
