Add ownership mechanism to DPDK Ethernet devices to avoid multiple management
of a device by different DPDK entities.
The port ownership mechanism is a good point to redefine the synchronization
rules in ethdev:
1. The port allocation and port release synchronization will be managed
by ethdev.
2. The port usage synchronization will be managed by the port owner.
3. The port ownership synchronization will be managed by ethdev.
4. DPDK entity which want to use a port safely must take ownership
before.
V2:
Synchronize ethdev port creation.
Synchronize port ownership mechanism.
Rename owner remove API to rte_eth_dev_owner_unset.
Remove "ethdev: free a port by a dedicated API" patch - passed to another
series.
Add "ethdev: fix port data reset timing" patch.
Cahnge owner get API to return int value and to pass copy of the owner
structure.
Adjust testpmd to the improved owner get API.
Adjust documentations.
V3:
Change RTE_ETH_FOREACH_DEV iterator to skip owned ports(Gaetan suggestion).
Prevent goto in set\unset APIs by adding internal API - this also adds reuse of
code(Konstantin suggestion).
Group all the shared processes variables in one struct to allow easy allocation
of it(Konstantin suggestion).
Take owner name truncation as warning and not as error(Konstantin suggestion).
Mark the new APIs as EXPERIMENTAL.
Rebase on top of master_net_mlx.
Rebase on top of "[PATCH v6 0/6] Fail-safe\ethdev: fix removal handling lack"
series.
Rebase on top of "[PATCH v5 0/8] Introduce virtual driver for Hyper-V/Azure
platforms" series.
Add "ethdev: fix used portid allocation" patch suggested by Konstantin.

ethdev: fix port data reset timing
ethdev: fix used portid allocation
ethdev: add port ownership
ethdev: synchronize port allocation
net/failsafe: free an eth port by a dedicated API
net/failsafe: use ownership mechanism to own ports
app/testpmd: adjust ethdev port ownership
