  Currently, upper-layer application could get queue state only
through pointers such as dev->data->tx_queue_state[queue_id],
this is not the recommended way to access it. So this patch
add get queue state when call rte_eth_rx_queue_info_get and
rte_eth_tx_queue_info_get API.

Note: After add queue_state field, the 'struct rte_eth_rxq_info' size
remains 128B, and the 'struct rte_eth_txq_info' size remains 64B, so
it could be ABI compatible.

V4->V5:
- Add acked-by
- add a note to the "New features" section to annouce the new feature.

V3->V4:
- update libabigail.abignore for removing the CI warnings

V2->V3:
- rewrite the commit log and delete the part Note
- rewrite tht comments for queue state
- move the queue_state definition locations

V1->V2:
- move queue state defines to public file

Yes. the CI is warning after I send the V3 with fix some comments.
Then I update liabigail.bignore, taking into account your comments with 
thomas and send the V4.

Are we sure this is a false positive? - it is being added mid-structure on the rx-side at least.
Shouldn't this be appended to the end - unless it is being sneaked into padding between fields.

I believe there was a padding, that's why it was suggested to squeeze it here.
