obscache: distinct 'clear' and 'reset'

We make a difference between basic invalidatiton (or lack of loading) and
'reset' (current cache data are invalid).

We can now ensure a non-None key when we start the update. This will allow us
to "update" the existing key instead of recomputing one from scratch. This is
more efficient and less racy.
