linux-gen: packet: implement references as copy
Implement packet references API as packet copy. This is the simplest way to support the API, as other packet functions are not affected at all.

validation: packet: remove non compatible tests
Tests for bad inputs are not compatible to the spec. Out-of-range values cause undefined results and must not be tested in validation suite.
Remove reference checks that do not comply anymore to the new odp_packet_has_ref() specification.

api: packet: references may be implemented as copy
Some implementations may implement new references as packet copy. odp_packet_has_ref() will return 0 for copies, since those are unique packets.

Introduce new APIs that support efficient sharing of portions of packets: * odp_packet_ref_static() creates a new static reference for a packet * odp_packet_ref() creates a new dynamic reference to a packet * odp_packet_ref_pkt() creates a reference to a packet with a supplied header packet * odp_packet_has_ref() checks if a packet has multiple references to it * odp_packet_unshared_len() returns the unshared data length of a reference
