[WIP] KUDU-1398 CFile index blocks can store shortest separating prefix

This changes the values stored as index keys to be a shortest key
between the first key of the data block and the last key of the previous
data block. This change does not apply to deltafiles or bloomfiles.
Deltafiles expect to be able to decode an index key into a DeltaKey.
Bloom files don't work with this change for reasons I haven't tracked
down yet.
