+ in many places, replace &V_layer3_chain with a local
variable chain;
+ bring the counter of rules and static_len within ip_fw_chain
replacing static variables;

+ document which lock protects certain data structures
- move global variables around to reduce the scope and make them

- remove duplicate static variables in different files;
