startup options for chunked items.

has spent some time under performance testing. For larger items there's less
than 5% extra CPU usage, however the max usable CPU when using large items is
1/10th or less before you run out of bandwidth. Mixed small/large items will
still balance out.

comments out debugging (which must be removed for release).

restores defaults and ensures only t/chunked-items.t is affected.

dyn-maxbytes and item_size_max tests still fail.

append/prepend aren't implemented, sasl needs to be guarded.

slab mover needs to be updated.
