[packages] babeld: new upstream release 1.4.2

INCOMPATIBLE CHANGE: the former option import_table is now a list in
/etc/config/babeld.

Default values for interface parameters, introduced in this release, are
not supported yet in UCI config.

19 June 2013: babeld-1.4.2

  * Extensive changes to the configuration parser.  It is now possible
    to set all command-line options from the configuration file, and
    to specify default values for interface parameters.
  * Allow redistributing routes from multiple kernel tables.  Thanks
    to Toke Høiland-Jørgensen.
  * Fix some whitespace issues in the configuration parser.
  * Fix a bug in the configuration parser that could give wrong values
    to some exotic interface parameters (channel and faraway).
  * Fix a bug that could cause some extra traffic at shutdown.  Thanks
    to Matthieu Boutier.
  * Under Linux, set rp_filter explicitly for all interfaces.  This
    avoids mysterious routing failures on distributions that set
    rp_filter by default.  Reported by Baptiste Jonglez.
