linux-gen: packet: roll back to copy based references
In order to re-implement segmentation for the new reference
implementation roll back to the copy based reference implementation,
which have been proved to work OK.
This zero copy reference implementation introduced multiple issues:
* segment pointers and length were not set correctly, but were
left to NULL
* reference counting has a race condition which causes random
assert failures also with non-reference packets
* there's larger than expected performance drop with
non-reference packets
* the first segment of a reference was zero bytes long, which
is possible by the API but is unusual for users

validation: packet: relax small concat test
Limit number of consecutive small concat to fraction of
the number of packets in the pool. An implementation linking
packets together (no copy) cannot be expected to support
one byte concats up to max packet size.

validation: packet: unshared len with static reference
When static references are used all data is shared, and thus
unshared length is zero. When there's no references, all data
is unique to the packet (unshared len == len).

linux-gen: packet: re-implement packet segmentation
Removed limitation to fixed number of segments
(CONFIG_PACKET_MAX_SEGS) per packet. Packet headers carrying
segment tables are now linked together with 'next_seg' pointer.
Last header containing a segment table is pointed by 'last_seg'
pointer. Other than the first segment are not referred directly
but with seg_entry_ functions.

linux-gen: packet: optimize header layout
Pack most often used data into the first and the last cache line
of buffer header, and the first cache line of packet header.
Reduce offsets and head-/tailroom fields to 16 bits, since
those are in maximum as large as a segment, usually much
less. Pack header fields into correct alignments (when possible),
so that holes are avoided.
These changes reduce packet header size by one cache line.
