Move part of isobusfs which can be reused by other applications to the
libj1939. By the way, reuse some of new libj1939 code in the j1939cat.

Modify the isobusfs_log function in isobusfs_cmn.c to explicitly limit
the lengths of the time_buffer, level_str, and log_entry strings in
the snprintf format string to 40, 10, and 150 characters respectively.
This change acknowledges that truncation may still occur, but it is now
explicit and controlled.
This change silences the following warning:

Kernel may notify us about some error, which may happens if the bus was
in the error state. But this is not a good reason to kill application,
especially the server side.
