The 'perf kwork' tool is used to trace time properties of kernel work
(such as irq, softirq, and workqueue), including runtime, latency, and
timehist, using the infrastructure in the perf tools to allow tracing
extra targets.

This is the first commit to reuse the 'perf record' framework code to
implement a simple record function, kwork is not supported currently.

Test cases:

  # perf

   usage: perf [--version] [--help] [OPTIONS] COMMAND [ARGS]

   The most commonly used perf commands are:
  <SNIP>
     iostat          Show I/O performance metrics
     kallsyms        Searches running kernel for symbols
     kmem            Tool to trace/measure kernel memory properties
     kvm             Tool to trace/measure kvm guest os
     kwork           Tool to trace/measure kernel work properties (latencies)
     list            List all symbolic event types
     lock            Analyze lock events
     mem             Profile memory accesses
     record          Run a command and record its profile into perf.data
  <SNIP>
   See 'perf help COMMAND' for more information on a specific command.

  # perf kwork

   Usage: perf kwork [<options>] {record}

      -D, --dump-raw-trace  dump raw trace in ASCII
      -f, --force           don't complain, do it
      -k, --kwork <kwork>   list of kwork to profile
      -v, --verbose         be more verbose (show symbol address, etc)

  # perf kwork record -- sleep 1
  [ perf record: Woken up 0 times to write data ]
  [ perf record: Captured and wrote 1.787 MB perf.data ]
