Jason Evans d227440524 Fix bugs: 
* Fix a race in chunk_dealloc_dss().

  * Check for allocation failure before zeroing memory in base_calloc().

Merge enhancements from a divergent version of jemalloc:

  * Convert thread-specific caching from magazines to an algorithm that is
    more tunable, and implement incremental GC.

  * Add support for medium size classes, [4KiB..32KiB], 2KiB apart by
    default.

  * Add dirty page tracking for pages within active small/medium object
    runs.  This allows malloc to track precisely which pages are in active
    use, which makes dirty page purging more effective.

  * Base maximum dirty page count on proportion of active memory.

  * Use optional zeroing in arena_chunk_alloc() to avoid needless zeroing
    of chunks.  This is useful in the context of DSS allocation, since a
    long-lived application may commonly recycle chunks.

  * Increase the default chunk size from 1MiB to 4MiB.

Remove feature:

  * Remove the dynamic rebalancing code, since thread caching reduces its
    utility.
