merge.applyupdates: call driverpreprocess before starting merge actions

We also need to update our internal state to whatever state driverpreprocess
leaves it in.

Adding an error state separate from the unresolved count is too big a
refactoring for now, so we hack around it by setting it to a positive value to
indicate an error state.
