FIX: coverty scan reveals some resourceleaks and overruns, which is supposed to be fixed now.

/armsrc/des.c   overflow 7 instead of 6
/client/cmdlfhitag.c  overflows traclen
/client/util.c   sprint_bin_break  overflows.
/client/cmdhficlass.c   need to free memory after malloc.

ADD:  RotateRight macro in util.h
