HBASE-20411 Ameliorate MutableSegment synchronize 

Change the MemStore size accounting so we don't synchronize across three
volatiles applying deltas. Instead:

 + Make MemStoreSize, a datastructure of our memstore size longs, immutable.
 + Undo MemStoreSizing being an instance of MemStoreSize; instead it has-a.
 + Make two MemStoreSizing implementations; one thread-safe, the other not.
 + Let all memory sizing longs run independent, untied by
   synchronize (Huaxiang and Anoop suggestion) using atomiclongs.
 + Review all use of MemStoreSizing. Many are single-threaded and do
   not need to be synchronized; use the non-thread safe counter.

TODO: Use this technique accounting at the global level too.
