The eventdev driver DLB was removed in DPDK 21.05,
breaking the ABI check.
The exception was agreed so we just need to skip this check.
Note: complete removal of a driver cannot be ignored
in devtools/libabigail.abignore, so the script must be patched.

The scripts gen-abi.sh and check-abi.sh are updated
to print error messages to stderr so they are likely never ignored.
When called from test-meson-builds.sh, the standard messages on stdout
can be more quiet depending on the verbosity settings.
The beginning of the ABI check is announced in verbose mode.
The commands are printed in very verbose mode.
The check result details are available in verbose mode.

abidiff can provide some more information about the ABI difference it
detected.
In all cases, a discussion on the mailing must happen but we can give
some hints to know if this is a problem with the script calling abidiff,
a potential ABI breakage or an unambiguous ABI breakage.

Having a special versioning for experimental/internal libraries put a
additional maintenance cost while this status is already announced in
MAINTAINERS and the library headers/documentation.
Following discussions and vote at 05/20 TB meeting [1], use a single
versioning for all libraries in DPDK.
Note: for the ABI check, an exception [2] had been added when tweaking
this special versioning [3].
Prefer explicit libabigail rules (which will be dropped in 20.11).

We don't provide ABI compatibility for experimental libraries.
Skip those libraries by catching a soname containing a version starting
with '0.'.
Align the special case for the glue libraries by using the soname too.
Once libabigail has support for it, we will have a single type of rule.

For normal developers, those checks are disabled.
Enabling them requires a configuration that will trigger the ABI dumps
generation as part of the existing devtools/test-build.sh and
devtools/test-meson-builds.sh scripts.
Those checks are enabled in the CI for the default meson options on x86
and aarch64 so that proposed patches are validated via our CI robot.
A cache of the ABI is stored in travis jobs to avoid rebuilding too
often.
Checks can be informational only, by setting ABI_CHECKS_WARN_ONLY when
breaking the ABI in a future release.
Explicit suppression rules have been added on internal structures
exposed to crypto drivers as the current ABI policy does not apply to
them.
This could be improved in the future by carefully splitting the headers
content with application and driver "users" in mind.
We currently have issues reported for librte_crypto recent changes for
which suppression rules have been added too.
Mellanox glue libraries are explicitly skipped as they are not part of
the application ABI.
