Default chunk is no longer embedded into the fifo and on free is
returned to its respective chunk list.

As opposed to growing, this is not a bulk operation, instead dependent
on how the producer/consumer advance head and tail, the fifo will shrink
in one or multiple steps.
Only once the fifo's nitems and size are reduced to their appropriate
values, equal or larger to what was requested, can the fifo chunks be
collected by the owner. Chunk collection must be done with the segment
heap pushed.

If head/tail are stored as "absolute" values that are normalized to [0,
fifo_size] interval, when fifo is shrunk/grown the consumer and producer
have to independently update to the new fifo size and fix head and tail,
respectively.
If the head and tail are stored as normalized values, under the right
conditions, they don't need to be fixed when fifo size changes.
This reverts one of the changes in gerrit 18223.

These were introduced with the switch to unbound tail/head size, so they
only affect master. Added unit tests to avoid future surprises.
