Fix #496 blind event clients after dev restart (attempt 2)
requested to merge github/fork/mliszcz/fix-496-blind-event-clients-after-dev-restart-attempt-2 into tango-9-lts
This PR restores Attribute::client_lib contents from temporary storage during DevReset handling.
Per original issue, attribute shall be identified by its name instead of index in multiattribute. This change is included as well but I was unable to reproduce this issue in a test (dynamic attribute created with IOAddAttribute was somehow persisted during the reset).
Fixes #496 (closed).
