Arnaldo Carvalho de Melo 25753e0396 pfunct: Use load stealer to speed up --class 
We were loading everything to then iterate looking for functions with
pointers to the --class argument, do it in the stealer and go on
ditching the already processed data, greatly speeding up the process.

  $ pfunct -c perf_event_attr
  security_perf_event_open
  register_user_hw_breakpoint
  modify_user_hw_breakpoint
  perf_event_create_kernel_counter
  register_wide_hw_breakpoint
  bpf_lsm_perf_event_open
  modify_user_hw_breakpoint_check
  perf_event_create_kernel_counter
  $
  $
  $ pfunct bpf_lsm_perf_event_open
  int bpf_lsm_perf_event_open(struct perf_event_attr * attr, int type);
  $

  $ for function in `pfunct -c perf_event_attr` ; do pfunct $function ; done
  int security_perf_event_open(struct perf_event_attr * attr, int type);
  struct perf_event * register_user_hw_breakpoint(struct perf_event_attr * attr, perf_overflow_handler_t triggered, void * context, struct task_struct * tsk);
  int modify_user_hw_breakpoint(struct perf_event * bp, struct perf_event_attr * attr);
  struct perf_event * perf_event_create_kernel_counter(struct perf_event_attr * attr, int cpu, struct task_struct * task, perf_overflow_handler_t callback, void * context);
  struct perf_event * * register_wide_hw_breakpoint(struct perf_event_attr * attr, perf_overflow_handler_t triggered, void * context);
  int bpf_lsm_perf_event_open(struct perf_event_attr * attr, int type);
  int modify_user_hw_breakpoint_check(struct perf_event * bp, struct perf_event_attr * attr, bool check);
  struct perf_event * perf_event_create_kernel_counter(struct perf_event_attr * attr, int cpu, struct task_struct * task, perf_overflow_handler_t callback, void * context);
