9d60f54569 common/mlx5: remove inclusion of Verbs header files
Several source files include Verbs header files as in (1). These source
files will not compile under non-Linux operating systems. This commit
removes this inclusion in two cases:

Case 1: There is no usage of ibv_* or mlx5dv_* symbols in the source
file so the inclusion in (1) can be safely removed.

Case 2: Verbs symbols are used. Please note the inclusion in (1) already
appears in file linux/mlx5_glue.h (which represents the interface
to the rdma-core library). Therefore, replace (1) in the source file
with (2).  Under non-Linux operating systems - file mlx5_glue.h will not
include (1).

(1)
 #include <infiniband/verbs.h>
 #include <infiniband/mlx5dv.h>

(2)
 #include <mlx5_glue.h>

d5ed8aa944 net/mlx5: add memory region callbacks in per-device cache
Prior to this commit MR operations were verbs based and hard coded under
common/mlx5/linux directory. This commit enables upper layers (e.g.
net/mlx5) to determine which MR operations to use. For example the net
layer could set devx based MR operations in non-Linux environments. The
reg_mr and dereg_mr callbacks are added to the global per-device MR
cache 'struct mlx5_mr_share_cache'.

58a17853b5 common/mlx5: export memory region Verbs operations
The glue verbs operations reg_mr and dereg_mr are wrapped and exported
in functions mlx5_common_verbs_reg_mr and mlx5_common_verbs_dereg_mr
respectively.  The exported functions are added to a new file
linux/mlx5_common_verbs.c.

56d2067735 common/mlx5: remove memory region dependency on Verbs
Replace 'struct ibv_mr *' (in 'struct mlx5_mr') with a new 'struct
mlx5_pmd_mr'.  The new struct contains the required MR field: lkey,
addr, len and is independent of ibv.

64c563f8b1 common/mlx5: mark internal symbols
Move mlx5 symbols in the map file to the INTERNAL section and add
__internal tags to their definitions.
Those symbols were exported in 20.02 and now (20.05) they are removed.
Avoid ABI comparison issues between 20.05/20.08 and 20.02 by adding the
suppress_file directive to libabigail.abignore file. This directive will
prevent loading mlx5 common symbols and no comparison will be performed.

In addition move symbols from the EXPERIMENTAL section to the INTERNAL
section.

b8dc6b0e29 common/mlx5: refactor memory management
Refactor common memory btree and cache management to common driver.
Replace some input parameters of MR APIs to more common data structure
like PD, port_id, share_cache,... so that multiple PMD drivers can
use those MR APIs.

Modify mlx5 net pmd driver to use MR management APIs from common driver.
