Add version info to debug outputfeature/debug-improvements

- Initialize the log at the start of ipmi_main() to allow for proper
  logging at the start;
- Remove the unused log_level_get() function;
- Update log_level_set() to take verbosity instead of log level
  (default verbosity is 0, which is LOG_NOTICE log level),
  use the function to update log level as `-v` is encountered
  in command line;
- Move IANA PEN list debugging to verbosity 6. The list is too long
  to see it in each debug output of verbosity 5 that is used for
  debugging lan/lanplus packets;
- For verbosity >= 2 (that is `-vv`) add the ipmitool version
  information at the start.
