Heikki Linnakangas e4670a5f1e Remove the PageVersions abstraction. ...

Since commit fdd987c3ad, it was only used in InMemoryLayers. Let's
just "inline" the code into InMemoryLayer itself.

I originally did this as part of a bigger PR (#1267). With that PR,
one in-memory layer, and one ephemeral file, would hold page versions
belonging to multiple segments. Currently, PageVersions can only hold
versions for a single segment, so that would need to be changed.
Rather than modify PageVersions to support that, just remove it
altogether.
