Once we add the ability to attach additional segments to a packet (as is
being discussed in other threads) we may wish to revisit the concept of
"extensible" headroom/tailroom. As long as packets can be extended there's
no logical reason why headroom/tailroom need be limited to a single segment.
Maximum headroom is defined in ODP_PACKET_MAX_HEADROOM and is an
implementation specific value and will not be greater than uint32/2.
Having said that the current definition of headroom in ODP is that it
will not exceed a single segment meaning the headroom will NOT
overflow by adding an empty

It can be used to restore headroom later. Does it possible a headroom
to be > sizeof(int32)/2?
