Previously, when re-mapping the slots, a slot ID could be assigned to more than one device, causing errors when searching for the right mapping (it would use the first found). Also assign new slot IDs for new found slots, avoiding previously used slot IDs. The last assigned slot ID is stored in the proxy structure in a new added field last_id.

The test covers a case where duplicate slots IDs were assigned to two different slots in the mapping. Signed-off-by: Anderson Toshiyuki Sasaki <ansasaki@redhat.com>

This PR supersedes #281
Previously, when assigning the slot IDs to the mapping, it could happen that new slots were listed by the module before slots previously seen. In this case duplicate slot IDs would be assigned to different slots.
This change makes all the reused slot IDs to be assigned before the new slot IDs. It also tries to make the slot IDs monotonically crescent.
A reproducer test case was added.
Fixes #266
