-------------------------------------------
    Attachment: HBASE-17484.patch

Patch for trunk. Creates OffheapKeyValue as an abstract class and MemstoreOffheapKeyValue and CachedKeyValue are its two variants.
When we do copyCellTo for the offheap case we create MemstoreOffheapKeyValue.

> After running lot of different performance tests for various scenarios and with multi threads we thought that is  better to have a version of OffheapKV in write path that does not cache anything and its fixed_overhead is equal to that in KeyValue.
