Move setting next protocol id field from higher protocols (ARP, IPv4)
to Ethernet. It makes code little more generic w/o checking each lower
protocol and setting specific field id.

Add set_next_proto callback to proto_hdr struct to allow lower
protocol set next protocol id by enum proto_id.
Extended proto_lower_default_add(...) function to take upper protocol
to delegate it's id to lower protocol to set next protocol field.

Change proto_header_init(...) and proto_lower_default_add(...)
functions to return struct proto_hdr * to do not call
proto_current_header(...) after, so it makes more sense to get struct
proto_hdr * right after initializing protocol by id.

The IEEE 802.3 standard commonly refers to the field specifying the
upper layer protocol as Ethertype, not protocol. Thus, also support the
keywords "etype" and "type" for this field.

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.
