> HBASE-4489 changed the default endKey on HexStringSplit from 7FFF... to FFFF...  While
this is correct, existing users of 0.90 RegionSplitter have 7FFF as the end key in their schema
and the last region will not split properly under this new code.  We need to let the user
specify a custom start/end key range for when situations like this arise.  Optimally, we should
also write the start/end key in META so we could figure this out implicitly instead of requiring
the user to explicitly specify it.
