gensio_set_log_mask, gensio_get_log_mask, gensio_log_level_to_str, - Logging and seting which gensio logs

       The  log  mask  is  a  global  variable  in the gensio library that sets what level of logs are delivered
       through the vlog function pointer in gensio_os_funcs.  Log levels are:

              GENSIO_LOG_FATAL GENSIO_LOG_ERR GENSIO_LOG_WARNING GENSIO_LOG_INFO GENSIO_LOG_DEBUG

       with obvious meanings.  There is also:

              GENSIO_LOG_MASK_ALL

       which is a bitmask of all the log levels.

       The default log mask is (1<<GENSIO_LOG_FATAL|1<<GENSIO_LOG_ERR).  Setting other log values  can  be
       helpful in debugging problems with gensios.

       gensio_log_level_to_str converts a log level to a string representation of that level.

       gensio_vlog  and  gensio_log are the functions used to generate logs.  These are primarily for use in the
       gensio library, though you may use them, too, if you like.
