api: datastore_status: restore api/gui compatibility

Browse Source 
the latest changes to this api call changed/removed some things that
were actually necessary for the gui. Readd those and document them this
time.

The change from u64 to i64 limits us to 8EiB of Datastore sizes (instead if
16EiB) but if we reach that, we must adapt most other parts to use 128bit
sizes anyway
