Now that everything that has ever accessed the shared memory
config is doing so through the public API's, we can make it
internal. Since we're removing quite a few headers from
rte_eal_memconfig.h, we need to add them back in places
where this header is used.
This bumps the ABI, so also change all build files and make
update documentation.

Replace the use of rte_get_timer_cycles() with getentropy() for
seeding the pseudo-random number generator. getentropy() provides a
more truly random value.
getentropy() requires glibc 2.25 and Linux kernel 3.17. In case
getentropy() is not found at compile time, or the relevant syscall
fails in runtime, the rdseed machine instruction will be used as a
fallback.
rdseed is only available on x86 (Broadwell or later). In case it is
not present, rte_get_timer_cycles() will be used as a second fallback.
On non-Meson builds, getentropy() will not be used.

Within EAL we had a series of if statements for selecting the EAL directory
to use. Now that the directory names match those of the OS's they are for
we can instead just use a generated subdirectory name, shortening the code.
To avoid strange errors, we still need to check for unsupported OS's, but
do this check up-front in the config meson.build file.

Since compat library is only a single header, we can easily move it into
the EAL common headers instead of tracking it separately. The downside of
this is that it becomes a little more difficult to have any libs that are
built before EAL depend on it. Thankfully, this is not a major problem as
the only library which uses rte_compat.h and is built before EAL (kvargs)
already has the path to the compat.h header file explicitly called out as
an include path.
However, to ensure that we don't hit problems later with this, we can add
EAL common headers folder to the global include list in the meson build
which means that all common headers can be safely used by all libraries, no
matter what their build order.
As a side-effect, this patch also fixes an issue with building on BSD using
meson, due to compat lib no longer needing to be listed as a dependency.

We use _GNU_SOURCE all over the place, but often times we miss
defining it, resulting in broken builds on musl. Rather than
fixing every library's and driver's and application's makefile,
fix it by simply defining _GNU_SOURCE by default for all
builds.
Remove all usages of _GNU_SOURCE in source files and makefiles,
and also fixup a couple of instances of using __USE_GNU instead
of _GNU_SOURCE.

Currently, command-line switches for legacy mem mode or single-file
segments mode are only stored in internal config. This leads to a
situation where these flags have to always match between primary
and secondary, which is bad for usability.
Fix this by storing these flags in the shared config as well, so
that secondary process can know if the primary was launched in
single-file segments or legacy mem mode.
This bumps the EAL ABI, however there's an EAL deprecation notice
already in place[1] for a different feature, so that's OK.

The kernel module source file directory passed via VPATH was wrong,
which caused the source files to be not found via make. Rather than
explicitly passing VPATH, make use of the fact that the full path
to the source files is passed by meson, so split that into directory
part - to be used as VPATH - and file part - to be used as the source
filename.

The EAL and compat libraries were special-cases in the library build
process, the former because of it's complexity, and the latter because
it only consists of a single header file.
By reworking the EAL meson.build files, we can eliminate the need for it to
be a special case, by having it build up and return the list of sources,
headers, and objects and return those to the higher level build file. This
should also simplify the building of EAL, as we can eliminate a number of
meson.build files that would no longer be needed, and have fewer, but
larger meson.build files (9 now vs 14 previous) - thereby making the logic
easier to follow and items easier to find.
Once done, we can pull eal into the main library loop, with some
modifications to support it. Compat can also be pulled it once we add in a
check to handle the case of an empty sources list.

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
