Subject: [PATCH 0/4] perf tools: Fix -g option handling

hi,
changing the '-g/-G' options for record/top commands
to take NO argument and enable unwind method based
on .perfconfig setup (using FP by default).

The current -g option parsing moves into the
'--call-graph' option.

Examples:
  $ cat ~/.perfconfig:
    [top]
          call-graph = fp

    [record]
          call-graph = dwarf,8192

  $ perf record -g ls
  - enables dwarf unwind with user stack size dump 8192 bytes

  $ perf top -G
  - enables frame pointer unwind

  $ perf record --call-graph=fp ls
  - enables frame pointer unwind

  $ perf top --call-graph=dwarf,4096 ls
  - enables dwarf unwind with user stack size dump 4096 bytes

thanks,
jirka
