This change removes the need to distinguish unlocked priv_*() functions
which are therefore renamed using a mlx5_*() prefix for consistency.
At the same time, all functions from mlx5 uses a pointer to the ETH device
instead of the one to the PMD private 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.

Create a rte_ethdev_driver.h file and move PMD specific APIs here.
Drivers updated to include this new header file.
There is no update in header content and since ethdev.h included by
ethdev_driver.h, nothing changed from driver point of view, only
logically grouping of APIs. From applications point of view they can't
access to driver specific APIs anymore and they shouldn't.
More PMD specific data structures still remain in ethdev.h because of
inline functions in header use them. Those will be handled separately.

The stats_get dev op API doesn't include return value, so PMD cannot
return an error in case of failure at stats getting process time.
Since PCI devices can be removed and there is a time between the
physical removal to the RMV interrupt, the user may get invalid stats
without any indication.
This patch changes the stats_get API return value to be int instead of
void.
All the net PMDs stats_get dev ops are adjusted by this patch.

The current Tx error counter counts, according to its description,
the total number of packets not sent when TX ring full. It is reported
to application as part of oerrors field.
The drop due to full ring is not the statistic that should be set on
oerrors field. Such number can be counted by the application using the
return value of the Tx burst function.
The number that should be set there is the number of packets the device
could not transmit in any way, even when it has resources.
Therefore, replace this counter to count the total number of failed
transmitted packets.

The corrupted code didn't unlock the spinlock in xstats
get and reset functions error flow.
Hence, if these errors happened, the device spinlock was
left locked and many mlx5 device functionalities were blocked.
The fix unlocks the spinlock in the missed places.

The number of extended statistics counters is queried through ETHTOOL.
ETHTOOL provides a different number when the link is up or down.
Since extended statistics query occurs at device start,
segmentation fault might happen when changing the link state before and
after the device start.
this commit address this issue, and query the number of statistics
before every call to ETHTOOL.
