-----------------------------------------------------------------

0.98 and branch-1 versions of patch (With deprecation of API in Cell)
Ping [~enis] for commit to branch-1
This needs to be in place for the 0.98 and RM confirmed.  So this will be very much needed
in branch-1 as well.. Pls review.

> 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.
