Add rte_flow_action_count action data structure to enable shared
counters across multiple flows on a single port or across multiple
flows on multiple ports within the same switch domain. Also this enables
multiple count actions to be specified in a single flow action.
This patch also modifies the existing rte_flow_query API to take the
rte_flow_action structure as an input parameter instead of the
rte_flow_action_type enumeration to allow querying a specific action
from a flow rule when multiple actions of the same type are specified.
This patch also contains updates for the bonding, failsafe and mlx5 PMDs
and testpmd application which are affected by this API change.

The query for the tunnel stateless offloads is wrongly implemented
because of:
1. It was using the device id to query for the offloads.
2. It was using a compilation flag for Verbs which no longer exits.
The main reason was lack of proper API from Verbs.
Fixing the query to use rdma-core API. The capability returned from
rdma-core refer to both Tx and Rx sides.
Eventhough there is a separate cap for GRE and VXLAN, implementation merge
them into a single flag in order to simplify the checks on the data

Several control operations implemented by these PMDs affect netdevices
through sysfs, itself subject to file system permission checks enforced by
the kernel, which limits their use for most purposes to applications
running with root privileges.
Since performing the same operations through ioctl() requires fewer
capabilities (only CAP_NET_ADMIN) and given the remaining operations are
already implemented this way, this patch standardizes on ioctl() and gets
rid of redundant code.

Reserving the memory space for the UAR near huge pages helps to
**reduce** the cases where the secondary process cannot start. Those
pages being physical pages they must be mapped at the same virtual
address as in the primary process to have a
working secondary process.
As this remap is almost the latest being done by the processes
(libraries, heaps, stacks are already loaded), similar to huge pages,
there is **no guarantee** this mechanism will always work.

Following commit c7bf62255e ("net/mlx5: fix handling link status event")
the link state must be up in order for the burst function to be set on
the device ops.
As the link may take time to move between down and up state it is
possible the rte_eth_dev_start call will return with wrong burst
function (either null or the empty burst function).
Fixing it by forcing the link to be up before returning from device
start. In case the link is still not up after 5 seconds fail the function.
In addition initialize the burst function on device probe to prevent
crashes before the link is up.

When no memory is available on the same numa node than the device, the
