buildtools/binutils-avx512-check.sh was Unix-only
and could not be used in cross builds:
1) written in shell;
2) used the assembler binary that may be missing,
e.g. when building on Windows with LLVM;
3) located the assembler as ${AS:-as} and referenced objdump,
but those binaries may be overridden via --cross-file.
Rewrite the script in Python.
Use the C compiler for the check.
Locate objdump and the C compiler using Meson.

The `doc` target used `echo` as its command.
On Windows, `echo` is always a shell built-in, there is no binary.
Starting from meson 0.58, `run_target()` always searches for command
executable and no longer accepts `echo` as such on Windows.
Replace plain `echo` with a Python one-liner.

If no enable_drivers option is passed, the default is to build
the drivers list by calling list-dir-globs.py.
But if no Python interpreter is installed, no error is reported
and all drivers end up being disabled.
Example on a minimal FreeBSD VM:
dpdk@freebsd:~/dpdk $ meson setup build
...
drivers:
common/cpt: not in enabled drivers build config
common/dpaax: not in enabled drivers build config
common/iavf: not in enabled drivers build config

common/octeontx: not in enabled drivers build config
common/octeontx2: not in enabled drivers build config

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).

Rather than checking the binutils version number, which can lead to
unnecessary disabling of AVX512 if fixes have been backported to distro
versions, we can instead check the output of "as" from binutils to see if
it is correct.
The check in the script uses the minimal assembly reproduction code posted
to the public bug tracker for gcc/binutils for those issues [1]. If the
binutils bug is present, the instruction parameters - specifically the
displacement parameter - will be different in the disassembled output
compared to the input. Therefore the check involves assembling a single
instruction and disassembling it again, checking that the two match.

If ibverbs_link is static and the application choose to link DPDK
as static libraries, both PMD and ibverbs libraries must be linked
as static libraries. And the dependencies of ibverbs (netlink) must
still be linked as shared libraries.
Unfortunately, meson forget about the static requirement for ibverbs
when generating the .pc file.
As a result, libibverbs, libmlx4, libmlx5 are listed in Requires.private
section (allowing to be linked as shared libraries) and libnl is missing.
A fix is in progress for meson, but anyway we will have to live without
such a fix until a better version of meson is widely available:
https://github.com/mesonbuild/meson/pull/6393
In order to avoid meson suggesting shared libraries in the section
Requires.private of the .pc file, the dependency object is recreated
with declare_dependency():
- cflags are extracted the libibverbs.pc
- ldflags, from libibverbs.pc, are processed to force
static flavor of ibverbs libraries, thanks to this syntax:
-l:libfoo.a

Rather than having to explicitly list each and every driver to disable in a
build, we can use a small python script and the python glob library to
expand out the wildcards. This means that we can configure meson using e.g.
meson -Ddisable_drivers=crypto/*,event/* build
to do a build omitting all the crypto and event drivers. Explicitly
specified drivers e.g. net/i40e, work as before, and can be mixed with
wildcarded drivers as required.

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.
