Fix lock ordering: when one has to allocate destination room for reclaiming, we have to unlock the data handle lock and acquire mc_lock, so we need to release the mc_lock before calling try_to_free_mem_chunk or try_to_reuse_mem_chunk. Also add a stressing disk reclaiming testcase.

Make a copy of the interface to the memchunk only when the latter gets detached from the data, and thus the interface code will not work on it. Drop the copy when the memchunk gets reattached. This allows interfaces to modify pointers in the interface in unpack, notably

rework deallocating handle memory chunks: we do not actually need to take the burden of going through the whole mc_list, since we already have the mc pointer. This also permits to properly mark per-worker chunks as deallocated

- Fix removed chunks locking: removed chunks actually never have to do with the handle any more, we shouldn't have to spinlock any header lock for them.
