Subject: few more fixes for iproute2/m_ipt

Comments:
1)optind according iptables sources have to be set to 0. If it is set to 1, in 
batch it will mess up things. Also in iptables sources i notice that ->tflags 
and ->used need to be reset.

2)Since target->t = fw_calloc(1, size); allocated memory in function build_st, 
it have to be freed at the end, or in batch we will have memory leak. TODO: 
Probably it must be freed in all "return -1" cases in parse_ipt after 
build_st. About this i am not sure, up to Stephen.

3)lname and new_name was malloc'ed, but not freed

Point 1 fix is critical, since without it m_ipt crashing iproute2 in batch 
mode.
