There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'

To help with consistency across all files, add a section to the
contributors guide on meson coding style. Although short, this covers
the basics for now, and can be extended in future as we see the need.

To allow support for additional build checks and tests only really
relevant for developers, we add support for a developer mode option to
DPDK. The default, "auto", value for this enables developer mode if a
".git" folder is found at the root of the source tree - as was the case
with the previous "make" build system. There is also support for
explicitly enabling or disabling this option using "meson configure" if
so desired.

To verify that all DPDK headers are ok for inclusion directly in a C file,
and are not missing any other pre-requisite headers, we can auto-generate
for each header an empty C file that includes that header. Compiling these
files will throw errors if any header has unmet dependencies.
For some libraries, there may be some header files which are not for direct
inclusion, but rather are to be included via other header files. To allow
later checking of these files for missing includes, we separate out the
indirect include files from the direct ones.
To ensure ongoing compliance, we enable this build test as part of the
default x86 build in "test-meson-builds.sh".

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)

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

number of build directories being present when testing patches. This
patchset modifies both scripts to use a DPDK_BUILD_TEST_DIR environment
variable to control where the build outputs are put.
For example, doing:
export DPDK_BUILD_TEST_DIR=__builds
./devtools/test-meson-builds.sh && ./devtools/test-build.sh \
x86_64-native-linux-clang+shared i686-native-linux-gcc

As per new ABI policy [1], all of the libraries are now versioned using
one global ABI version. Stable libraries use the MAJOR.MINOR ABI
version for their shared objects, while experimental libraries
use the 0.MAJORMINOR convention for their versioning.
Experimental library versioning is managed globally. Changes in this
patch implement the necessary steps to enable that.
The CONFIG_RTE_MAJOR_ABI option was introduced to permit multiple
DPDK versions installed side by side. The problem is now addressed
through the new ABI policy, and thus can be removed.
[David] For external libraries relying on Makefile, LIBABIVER is
preserved to avoid using DPDK global ABI version.
