data_smart: implement missing remote datastore operations

Enable the following operations from a remote datastore to affect the
other end:

* setVarFlag()
* delVar()
* delVarFlag()
* renameVar()

In practice I don't expect these to be used much, but they should be
present so that the implementation is at least reasonably filled out
and that the tests pass.

Also add tests for the interface, mostly by subclassing the existing
local test classes so that they are using a remote datastore. (These
don't actually test remote usage via tinfoil, just that the
datastore's interface can be used.)
