Add non-EAL libraries to DPDK build. The compat lib is a special case,
along with the previously-added EAL, but all other libs can be build using
the same set of commands, where the individual meson.build files only need
to specify their dependencies, source files, header files and ABI versions.

Support building the EAL with meson and ninja. This involves a number of
different meson.build files for iterating through all the different
subdirectories in the EAL. The library itself will be compiled on build but
the header files are only copied from their initial location once "ninja
install" is run. Instead, we use meson dependency tracking to ensure that
other libraries which use the EAL headers can find them in their original
locations.
Note: this does not include building kernel modules on either BSD or Linux

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.

This patch enables the NXP DPAA & DPAA2 drivers for
ARMV8 targets. They can be used with standard armv8 config
with command line mempool argument or newly introduced
platform mempool internal registration mechanism.
Note that the dpaa(x) specific config files are still preserved
to continue customer support. They also contain some of the ARM
performance tuning flags. e.g the default ARM cache size of 128
is not optimal for NXP platforms.
However, these configs will eventually be removed once a dynamic
mechanisms are developed to detect the performance settings.

On thunderx and octeontx, ring_perf_autotest and
ring_pmd_perf_autotest test shows better performance
when disabling CONFIG_RTE_RING_USE_C11_MEM_MODEL.
On the other hand, Enabling CONFIG_RTE_RING_USE_C11_MEM_MODEL
shows better performance on thunderx2.
Since thunderx2 is using the default armv8 config,

This patch is to support C11 memory model barrier in librte_ring.
There are 2 barrier implementation options in librte_ring (suggested
by Jerin).
1. use rte_smp_rmb
2. use load_acquire/store_release(refer to [1]).
The reason why providing 2 options is the performance benchmark
difference in different arm machines, refer to [2].
CONFIG_RTE_RING_USE_C11_MEM_MODEL is provided, and by default it is "n"
on any architectures and only "y" on arm64 so far.

This patch adds support for handling run-time driver arguments.
We have removed config option for per VF Tx switching and added
a run-time argument vf_txswitch. By default, the VF Tx switching is
enabled however it can be disabled using run-time argument.
Sample usage to disable per port VF Tx switching is something like...
-w 05:00.0,vf_txswitch=0 -w 05:00.1,vf_txswitch=0

This patch provides an option to do rte_memcpy() using 'restrict'
qualifier, which can induce GCC to do optimizations by using more
efficient instructions, providing some performance gain over memcpy()
on some ARM64 platforms/enviroments.
The memory copy performance differs between different ARM64
platforms. And a more recent glibc (e.g. 2.23 or later)
can provide a better memcpy() performance compared to old glibc
versions. It's always suggested to use a more recent glibc if
possible, from which the entire system can get benefit. If for some
reason an old glibc has to be used, this patch is provided for an
alternative.
This implementation can improve memory copy on some ARM64
platforms, when an old glibc (e.g. 2.19, 2.17...) is being used.
It is disabled by default and needs "RTE_ARCH_ARM64_MEMCPY"
defined to activate. It's not always proving better performance
than memcpy() so users need to run DPDK unit test
"memcpy_perf_autotest" and customize parameters in "customization
section" in rte_memcpy_64.h for best performance.
Compiler version will also impact the rte_memcpy() performance.
It's observed on some platforms and with the same code, GCC 7.2.0
compiled binary can provide better performance than GCC 4.8.5. It's
suggested to use GCC 5.4.0 or later.

OPDL ring is the core infrastructure of OPDL PMD. OPDL ring library
provide the core data structure and core helper function set. The Ring
implements a single ring multi-port/stage pipelined packet distribution
mechanism. This mechanism has the following characteristics:
• No multiple queue cost, therefore, latency is significant reduced.
• Fixed dependencies between queue/ports is more suitable for complex.
fixed pipelines of stateless packet processing (static pipeline).
• Has decentralized distribution (no scheduling core).
• Packets remain in order (no reorder core(s)).
* Update build system to enable compilation.

Without this patch, the number of queues per i40e VF is set to 4
by CONFIG_RTE_LIBRTE_I40E_QUEUE_NUM_PER_VF=4 in config/common_base.
It is a fixed value determined at compile time and can't be changed
at run time.
With this patch, the number of queues per i40e VF can be determined
at run time. For example, if the PCI address of an i40e PF is
aaaa:bb.cc, with the EAL parameter -w aaaa:bb.cc,queue-num-per-vf=8,
the number of queues per VF created from this PF is set to 8.
If there is no "queue-num-per-vf" setting in EAL parameters, it uses
the default value of 4. And if the value after the "queue-num-per-vf"
is invalid, it will also use the default value. The valid values can
be 1, 2, 4, 8, or 16.
