TupleBuckets in Riak objects

Browse source 
Adds support with test for tuplebuckets in Riak keys.

This exposed that there was no filter using the seglist on the in-mmemory keys.  This means that if there is no filter applied in the fold_function, many false positives may emerge.

This is probably not a big performance benefit (and indeed for performance it may be better to apply during the leveled_pmem:merge_trees).

Some thought still required as to what is more likely to contribute to future bugs: an extra location using the hash matching found in leveled_sst, or the extra results in the query.
