Since MR management has moved to the common area, there is no longer a
need for the DMA map and unmap function for each driver.
This patch share those functions. For most drivers it supports these
operations for the first time.

Add internal API to register mempools, that is, to create memory
regions (MR) for their memory and store them in a separate database.
Implementation deals with multi-process, so that class drivers don't
need to. Each protection domain has its own database. Memory regions
can be shared within a database if they represent a single hugepage
covering one or more mempools entirely.
Add internal API to lookup an MR key for an address that belongs
to a known mempool. It is a responsibility of a class driver
to extract the mempool from an mbuf.

All the mlx5 drivers using MRs for data-path must unregister the mapped
memory when it is freed by the dpdk process.
Currently, only the net/eth driver unregisters MRs in free event.
Move the net callback handler from net driver to common.

mlx5 PMD created the MR (Memory Region) resource on the
mlx5_dma_map call to make the memory available for DMA
operations. On the mlx5_dma_unmap call the MR resource
was not freed but inserted to MR Free list for further
garbage collection.
Actual MR resource destroying happened on device stop
call. That caused the runtime out of memory in case of
application performed multiple DMA map/unmap calls.
The fix immediately frees the MR resource on mlx5_dma_unmap
call not engaging the list. The export for mlx5_mr_free
function from common PMD part is added as well.

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).

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'.

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.

like PD, port_id, share_cache,... so that multiple PMD drivers can
use those MR APIs.
