This commit is a part for the DV counter optimization.
The batch counter dcs id starts from 0x800000 and none batch counter
starts from 0. As currently, the counter is changed to be indexed by
pool index and the offset of the counter in the pool counters_raw array.
It means now the counter index is same for batch and none batch counter.
Add the 0x800000 batch counter offset to the batch counter index helps
indicate the counter index is from batch or none batch container pool.

In the current state, when preforming read/write
transactions we must wait for a completion in order
to run the next transaction, and all transactions are
performed by order.
Relaxed Ordering is a PCI optimization which by enabling it
we allow the system to perform read/writes in a different
order without having to wait for completion and improve
the performance in that matter.
This commit introduces the creation of relaxed ordering
memory regions in mlx5.
As relaxed ordering is an optimization, drivers that
do not support it can simply ignore it and therefore
it is enabled by default.

This patch adds to MLX5 PMD the support of matching on IPv4 TTL and
IPv6 hoplimit.
Support is valid when using DV flow engine (Verbs flow engine doesn't
support matching on this field).

To provide the better PCIe bandwidth utilization the ConnectX-4LX
NIC supports the multi-packet write (MPW) sessions allowing to
pack multiple packets into one descriptor (WQE). This is legacy
feature and it has some limitations on the packets and data
description segments. To provide the best performance all inline
packets must be put into shared data segment and the total length
of MPW session must be limited. The limit is controlled with
txq_inline_mpw devarg.

As an arrangement to the vitrio queues creation, a 2 QPs and CQ may be
created for the virtio queue.
The design is to trigger an event for the guest and for the vdpa driver
when a new CQE is posted by the HW after the packet transition.
This patch add the basic operations to create and destroy the above HW
objects and to trigger the CQE events when a new CQE is posted.

Use the MLX5_ASSERT macros instead of the standard assert clause.
Depends on the RTE_LIBRTE_MLX5_DEBUG configuration option to define it.
If RTE_LIBRTE_MLX5_DEBUG is enabled MLX5_ASSERT is equal to RTE_VERIFY
to bypass the global CONFIG_RTE_ENABLE_ASSERT option.
If RTE_LIBRTE_MLX5_DEBUG is disabled, the global CONFIG_RTE_ENABLE_ASSERT
can still make this assert active by calling RTE_VERIFY inside RTE_ASSERT.

QP creation is needed for vDPA virtq support.
Add 2 DevX commands to create QP and to modify QP state.
The support is for RC QP only in force loopback address mode.
By this way, the packets can be sent to other inernal destinations in
the nic. For example: other QPs or virtqs.

Virtio emulation offload allows SW to offload the I/O operations of a
virtio virtqueue, using the device, allowing an improved performance
for its users.
While supplying all the relevant Virtqueue information (type, size,
memory location, doorbell information, etc.). The device can then
offload the I/O operation of this queue, according to its device type
characteristics.
Some of the virtio features can be supported according to the device
capability, for example, TSO and checksum.
Add virtio queue create, modify and query DevX commands.

A new Mellanox vdpa PMD will be added to support vdpa operations by
Mellanox adapters.
This vdpa PMD design includes mlx5_glue and mlx5_devx operations and
large parts of them are shared with the net/mlx5 PMD.
Create a new common library in drivers/common for mlx5 PMDs.
Move mlx5_glue, mlx5_devx_cmds and their dependencies to the new mlx5
common library in drivers/common.
The files mlx5_devx_cmds.c, mlx5_devx_cmds.h, mlx5_glue.c,
mlx5_glue.h and mlx5_prm.h are moved as is from drivers/net/mlx5 to
drivers/common/mlx5.
Share the log mechanism macros.
Separate also the log mechanism to allow different log level control to
the common library.
Build files and version files are adjusted accordingly.
Include lines are adjusted accordingly.
