> We store each tag's length and total tags length with 2 bytes in KeyValue buffer, HFiles
etc and we treat these lengths as short through out the code.  So the max length can be Short.MAX_VALUE.
  We can treat these lengths as unsigned and +ve always.  So we can actually treat these lengths
as int and store with 2 bytes so that the max length can reach 65535.
