net: Pass net through ip fragmention

This is the next installment of my work to pass struct net through the
output path so the code does not need to guess how to figure out which
network namespace it is in, and ultimately routes can have output
devices in another network namespace.

This round focuses on passing net through ip fragmentation which we seem
to call from about everywhere.  That is the main ip output paths, the
bridge netfilter code, and openvswitch.  This has to happend at once
accross the tree as function pointers are involved.

First some prep work is done, then ipv4 and ipv6 are converted and then
temporary helper functions are removed.
