wireprotov2server: port to emitrevisions()

We now have a proper storage API to request data on multiple
revisions. We can drop it into wire protocol version 2 with
minimal effort.

The new API handles pretty much everything we were doing manually to
build up the delta request. So we were able to delete a lot of code.

As a bonus, wireprotov2 code is no longer accessing some low-level
storage APIs. This includes the assumption that a node has an
associated numeric revision number! This should make it drastically
simpler to implement a server that doesn't have the concept of
revision numbers.
