Jiri Olsa 85723885fe perf record: Add --all-user/--all-kernel options
Allow user to easily switch all events to user or kernel space with simple
--all-user or --all-kernel options.

This will be handy within perf mem/c2c wrappers to switch easily monitoring
modes.

Committer note:

Testing it:

  # perf record --all-kernel --all-user -a sleep 2
   Error: option `all-user' cannot be used with all-kernel
   Usage: perf record [<options>] [<command>]
      or: perf record [<options>] -- <command> [<options>]

        --all-user        Configure all used events to run in user space.
        --all-kernel      Configure all used events to run in kernel space.
  # perf record --all-user --all-kernel -a sleep 2
   Error: option `all-kernel' cannot be used with all-user
   Usage: perf record [<options>] [<command>]
      or: perf record [<options>] -- <command> [<options>]

        --all-kernel      Configure all used events to run in kernel space.
        --all-user        Configure all used events to run in user space.
  # perf record --all-user -a sleep 1
