05ccc9d8a9 net/qede: fix port reconfiguration
This patch fixes deallocation of all fastpath resources unconditionally,
when re-configuring the device. When re-allocating resources PMD depends
on application to explicitly setup the Rx/Tx queue.

Deallocation of all the resources is only required if the Rx/Tx queue
configuration changes. For other scenarios like KNI MTU change we'd keep
existing configuration.

5af61440dd net/mlx5: fix flow counter container resize
The design of counter container resize used double buffer algorithm in
order to synchronize between the query thread to the control thread.
When the control thread detected resize need, it created new bigger
buffer for the counter pools in a new container and change the container
index atomically.
In case the query thread had not detect the previous resize before a new
one need was detected by the control thread, the control thread returned
EAGAIN to the flow creation API used a COUNT action.

The rte_flow API doesn't allow unblocked commands and doesn't expect to
get EAGAIN error type.

So, when a lot of flows were created between 2 different periodic
queries, 2 different resizes might try to be created and caused EAGAIN
error.
This behavior may blame flow creations.

Change the synchronization way to use lock instead of double buffer
algorithm.

The critical section of this lock is very small, so flow insertion
rate should not be decreased.

3a2cd6fd06 eal: fix C++17 compilation
Compiling a C++ application that includes directly or indirectly
rte_common.h will cause a warning:

include/rte_common.h:350:37: warning: ISO C++17 does not allow
  ‘register’ storage class specifier [-Wregister]
 rte_combine32ms1b(register uint32_t x)

C++ is pickier than standard C and flags this antique usage.

The register keyword is an old K&R legacy and should be removed
everywhere in DPDK. For now, fix it where it hurts.

05a38d7c75 compat: provide experimental alias for matured ABI
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)

45a4103e68 doc: fix default symbol binding in ABI guide
The document abi_versioning.rst incorrectly instructs the developer to
add BIND_DEFAULT_SYMBOL to the public header, not the source file. This
commit fixes the issue and adds some clarifications.

The commit also clarifies the use of use_function_versioning in the
meson/ninja build system, and does some minor re-organization of the
document.
