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.

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.

net/mlx5: fix Tx doorbell write memory barrier

As the result of testing it was found that some hosts have
the performance penalty imposed by required write memory barrier
after doorbell writing. Before 19.08 release there was some
heuristics to decide whether write memory barrier should be
performed. For the bursts of recommended size (or multiple)
it was supposed there were some extra ongoing packets in the
next burst and write memory barrier may be skipped (supposed
to be performed in the next burst, at least after descriptor
writing).

This patch restores that behaviour, the devargs tx_db_nc=2
must be specified to engage this performance tuning feature.

net/mlx5: check metadata registers availability

The metadata registers reg_c provide support for TAG and
SET_TAG features. Although there are 8 registers are available
on the current mlx5 devices, some of them can be reserved.
The availability should be queried by iterative trial-and-error
implemented by mlx5_flow_discover_mreg_c() routine.

If reg_c is available, it can be regarded inclusively that
the extensive metadata support is possible. E.g. metadata
register copy action, supporting 16 modify header actions
(instead of 8 by default) preserving register across
different domains (FDB and NIC) and so on.

net/mlx5: fix DevX event registration timing

The DevX counter management triggers an asynchronous event to get back
the new counters values from the HW.

The counter management doesn't trigger 2 parallel events for the same
pool, hence, the pool cannot be updated again in the event waiting time.

When the port is stopped, the DevX event mechanism wrongly was
destroyed what remained all the waiting pools in waiting state forever.

As a result, the counters of the stuck pools were never updated again.

Separate the DevX interrupt installation from the dev installation and
remove the DevX interrupt unregistration\registration from the
stop\start operations.

Now, the DevX interrupt should be installed in probe and uninstalled in
close.

sibling devices created in the current probe() loop belong

done on returned success of current probe()). This patch
