Currently, when flow destroyed, some memory resources may still be kept
as cached to help next time create flow more efficiently.
Some system may need the resources to be more flexible with flow create
and destroy. After peak time, with millions of flows destroyed, the
system would prefer the resources to be reclaimed completely, no cache
is needed. Then the resources can be allocated and used by other
components. The system is not so sensitive about the flow insertion
rate, but more care about the resources.
Both DPDK mlx5 PMD driver and the low level component rdma-core have
provided the flow resources to be configured cached or not, but there is
no APIs or parameters exposed to user to configure the flow resources
cache mode. In this case, introduce a new PMD devarg to let user
configure the flow resources cache mode will be helpful.
This commit is to add a new "reclaim_mem_mode" to help user configure if
the destroyed flows' cache resources should be kept or not.
Their will be three mode can be chosen:
1. 0(none). It means the flow resources will be cached as usual. The
resources will be cached, helpful with flow insertion rate.
2. 1(light). It will only enable the DPDK PMD level resources reclaim.
3. 2(aggressive). Both DPDK PMD level and rdma-core low level will be
configured as reclaimed mode.
With these three mode, user can configure the resources cache mode with
different levels.

With Doxygen 1.8.18, a warning appears when tagging
the main markdown header with {#index}.
That's why the tag has been removed from the API index in DPDK 20.05.
Unfortunately it makes the index page classified as a standard
"related page" instead of being the "main page".
The tag {#mainpage} could be used instead of {#index}.
Another solution, chosen here, is to specify the main page file
in the Doxygen configuration with the variable USE_MDFILE_AS_MAINPAGE.

For the ABI compatibility it is better to hide internal data structures
from the application as much as possible. But because of some inline
functions 'struct eth_dev_ops' can't be hidden completely.
Plan is to split the 'struct eth_dev_ops' into two as ones used by
inline functions and ones not used, and hide the second part that not
used by inline functions completely to the application.
Because of ABI break the work will be done in 20.11

On v20.02 some APIs matured and symbols moved from EXPERIMENTAL to
DPDK_20.0.1 block.
This had the affect of breaking the applications that were using these
APIs on v19.11. Although there is no modification of the APIs and the
action is positive and matures the APIs, the affect can be negative to
applications.
When a maintainer is promoting an API to become part of the next major
ABI version by removing the experimental tag. The maintainer may
choose to offer an alias to the experimental tag, to prevent these
breakages in future.
The following changes are made to enabling aliasing:
Updated to the ABI policy and ABI versioning documents.
Created VERSION_SYMBOL_EXPERIMENTAL helper macro.
Updated the 'check-symbols.sh' tool, which was complaining that the
symbol is in EXPERIMENTAL tag in .map file but it is not in the
.experimental section (__rte_experimental tag is missing).
Updated tool in a way it won't complain if the symbol in the
EXPERIMENTAL tag duplicated in some other block in .map file (versioned)
