Paweł Dziepak 5ff699e09f row_cache: rework cache to use fast forwarding reader ...

This uncomfortably large patch overhauls cache range reader so that it
can take advantage of fast forwarding mutation readers.

A significant change in the cache itself is that the continuity flag now
is used to determine whether cache is contiguous between the previous
entry and the current one. This allows for a significant simplification
of the cache code and easier integration with reader fast forwarding.
