trafgen: l3: Add IPv4 header generation backend
Add L3 module for implement L3 layer protocols generation.
Implemented setting of IPv4 header with all fields except options.
By default IPv4 address of output device is used as src ip address.
On finish (after packet is specified) - total len & checksum are calculated.
Meanwhile Ethernet protocol is initialized as default lower header.
If the lower protocol is IPv4 then IPv4 protocol id is set
to IP-in-IP in lower protocol header.
