Define the public API for trace support.
This patch also adds support for the build infrastructure and
update the MAINTAINERS file for the trace subsystem.
The 8 bytes tracepoint object is a global variable, and can be used in
fast path. Created a new __rte_trace_point section to store the
tracepoint objects as,
- It is a mostly read-only data and not to mix with other "write"
global variables.
- Chances that the same subsystem fast path variables come in the same
fast path cache line. i.e, it will enable a more predictable
performance number from build to build.

The libibverbs (and libmlx4/5) can be statically embedded
in the shared PMD library, or in the application with the static PMD.
It was supported with make build system in
commit 2c0dd7b69f ("config: add static linkage of mlx dependency").
The same feature is enabled with meson when using pkg-config
(i.e. only if the call to dependency() is successful).
The fallback method for searching library with cc.find_library()
is not supported because the dependencies of the found library
would not be linked (no such info in .a file unlike .so).
The main difference, in meson build system, is the generated .pc file
giving arguments to link DPDK with the application.
Unfortunately the .pc file will not keep memory of the static linkage
option for libibverbs.

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.

Compile Mellanox driver when its external dependencies are met. A
glue version of the driver can still be requested by using the
-Denable_driver_mlx_glue=true
Meson will try to find the required external libraries. When they are
not installed system wide, they can be provided though CFLAGS, LDFLAGS
and LD_LIBRARY_PATH environment variables, example (considering
RDMA-Core is installed in /tmp/rdma-core):
# CLFAGS=-I/tmp/rdma-core/build/include \
LDFLAGS=-L/tmp/rdma-core/build/lib \
LD_LIBRARY_PATH=/tmp/rdma-core/build/lib \
meson output
# LD_LIBRARY_PATH=/tmp/rdma-core/build/lib \
ninja -C output install
Note: LD_LIBRARY_PATH before ninja is necessary when the meson
configuration has changed (e.g. meson configure has been called), in
such situation the LD_LIBRARY_PATH is necessary to invoke the
autoconfiguration script.

This patch enables the test/test app to be built. It also adds
the test binary to be a meson-test, which allows the meson test
infrastructure to be used to run tests.
Tests are listed using the same test binary, however each test
sets a different DPDK_TEST environment variable. The string contents
of this DPDK_TEST env var is entered in the command line interface.
As such, the familiar test names such as "ring_perf_autotest" etc
are valid tests to run using this meson test infrastructure.
Note that the tests are run serially, given that we cannot run
multiple primary processes at a time. As each test must initialize
EAL this takes some time depending on the number of hugepages.
In future, we could improve this to run multiple tests from one
EAL init, but it is out of scope for this patchset.
Finally, an option to build the tests is added to the meson build
options. When disabled, the unit test code in test/test is not
compiled. The default is set to 'true'. To disable, run:
$ meson configure -Dtests=false

Add support for having selected example apps built as part of a meson,
ninja build. By default none are built, and those to be built should be
named directly in the -Dexamples='' meson configuration argument.
This is useful for developers working on a feature who want to use a
suitable example, or examples, to test that feature, as they can compile
everything up in one go, and run the example without having to do a ninja
install first.
This commit adds examples which don't consist of multiple apps in
subdirectories to the meson build, so they can be built by default by
passing -Dexamples parameter to meson.
Not included are the following examples:
* ethtool
* multi-process
* netmap_compat
* performance-thread
* quota_watermark
* server_node_efd
* vm_power_manager
To test the apps added here, use the following command, merged to one line,
to add them to your meson build (command to be run inside the build
directory):
meson configure -Dexamples=bbdev_app,bond,cmdline,distributor,\
eventdev_pipeline_sw_pmd, exception_path,helloworld,\
ip_fragmentation,ip_pipeline,ip_reassembly, ipsec-secgw,\
ipv4_multicast,kni,l2fwd-cat,l2fwd-crypto,l2fwd-jobstats,\
l2fwd-keepalive,l2fwd,l3fwd-acl,l3fwd-power,l3fwd-vf,l3fwd,\
link_status_interrupt,load_balancer,packet_ordering,ptpclient,\
qos_meter,qos_sched,rxtx_callbacks,skeleton,tep_termination,\

To build with meson and ninja, we need some initial infrastructure in
place. The build files for meson always need to be called "meson.build",
and options get placed in meson_options.txt
This commit adds a top-level meson.build file, which sets up the global
variables for tracking drivers, libraries, etc., and then includes other
build files, before finishing by writing the global build configuration
header file and a DPDK pkgconfig file at the end, using some of those same
globals.
From the top level build file, the only include file thus far is for the
config folder, which does some other setup of global configuration
parameters, including pulling in architecture specific parameters from an
architectural subdirectory. A number of configuration build options are
provided for the project to tune a number of global variables which will be
used later e.g. max numa nodes, max cores, etc. These settings all make
their way to the global build config header "rte_build_config.h". There is
also a file "rte_config.h", which includes "rte_build_config.h", and this
file is meant to hold other build-time values which are present in our
current static build configuration but are not normally meant for
user-configuration. Ideally, over time, the values placed here should be
moved to the individual libraries or drivers which want those values.
