Improve checksum calculation and address checking

1. Add a function that calculates the checksum of all the packet
   components starting from the specified position. This
   simplifies the code a bit and makes it easier to translate
   nested packets like ICMP error messages.

2. Don't hardcode IP source and destination addresses. This is
   required to translate ICMP error messages.
