In the next commit, we'll start using the batcher to eliminate mutex traffic. To avoid cluttering up that commit with the random bits of busy-work it entails, we'll centralize them here. This commit introduces: - A batched bin type. - The ability to mix batched and unbatched bins in the arena. - Conf parsing to set batches per size and a max batched size. - mallctl access to the corresponding opt-namespace keys. - Stats output of the above.
