--------------------------------------------------------------------------
All tests seems to pass. So with this patch as Prefix Tree is enabled back, we
can ensure that the value part is not copied while comparing the KVs when
EncodedSeekers.getKeyValue() is called. Wiill be a huge gain in cases like
MOB. Related to HBASE-10801 where other DBE algo were changed except for
PrefixTree.
