Jiri Olsa b39b839309 perf tools: Add parse_events_error interface 
Adding support to return error information from parse_events function.
Following struct will be populated by parse_events function on return:

  struct parse_events_error {
    int   idx;
    char *str;
    char *help;
  };

where 'idx' is the position in the string where the parsing failed,
'str' contains dynamically allocated error string describing the error
and 'help' is optional help string.

The change contains reporting function, which currently does not display
anything. The code changes to supply error data for specific event types
are coming in next patches. However this is what the expected output is:

  $ sudo perf record -e 'sched:krava' ls
  event syntax error: 'sched:krava'
                       \___ unknown tracepoint
  ...

  $ perf record -e 'cpu/even=0x1/' ls
  event syntax error: 'cpu/even=0x1/'
                           \___ unknown term

  valid terms: pc,any,inv,edge,cmask,event,in_tx,ldlat,umask,in_tx_cp,offcore_rsp,config,config1,config2,name,period,branch_type
  ...

  $ perf record -e cycles,cache-mises ls
  event syntax error: '..es,cache-mises'
                                 \___ parser error
  ...

The output functions cut the beginning of the event string so the error
starts up to 10th character and cut the end of the string of it crosses
the terminal width.
