Incompatible with OpenDNSSEC 2.1.13 : key handles are not shared between sessions

If we don't have any answer from the OpenDNSSEC team we would have to change the implementation to have one unique object Db per Token/Slot.

Can we add an option to support this (which would be disabled by default)?

Adding an option like that would add more complexity in the code.
The mitigation for this problem is to have one single cache per NetHSM/Slot instead of a cache per session. We could just change the cache to be per slot and that would work for every application. The only drawback being that the cache may stay invalid for longer and that could be fixed by a better handling of errors.

Sounds fine for me.
