Resource reclaimation implementation was splitted from the original series, and has already been part of RCU library. Rework the series to base LPM integration on RCU reclaimation APIs. New API rte_lpm_rcu_qsbr_add is introduced for application to register a RCU variable that LPM library will use. This provides user the handle to enable RCU that integrated in LPM library. Functional tests and performance tests are added to cover the integration with RCU. --- v6: Remove ALLOW_EXPERIMENTAL_API from rte_lpm.c. v5: No default value for reclaim_thd. This allows reclamation triggering with every call. Pass LPM pointer instead of tbl8 as argument of reclaim callback free function. Updated group_idx check at tbl8 allocation. Use enums instead of defines for different reclamation modes. RCU QSBR integrated path is inside ALLOW_EXPERIMENTAL_API to avoid ABI change. v4: Allow user to configure defer queue: size, reclaim threshold, max entries. Return defer queue handler so user can manually trigger reclaimation. Add blocking mode support. Defer queue will not be created.
