During LTO build compiler reports some 'false positive' warnings about
variables being possibly used uninitialized. This patch silences these
warnings.
Exemplary compiler warning to suppress (with LTO enabled):
error: ‘stats.greatest_free_size’ may be used uninitialized in this
function [-Werror=maybe-uninitialized]
return len - overhead;

Rather than dereference the mem_config internal structure, we can rely
on the rte_memzone_walk API and count memzones.

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.

Since all other apps have been moved to the "app" folder, the autotest app
remains alone in the test folder. Rather than having an entire top-level
folder for this, we can move it back to where it all started in early
versions of DPDK - the "app/" folder.
This move has a couple of advantages:
* This reduces clutter at the top level of the project, due to one less
folder.
* It eliminates the separate build task necessary for building the
autotests using make "make test-build" which means that developers are
less likely to miss something in their own compilation tests
* It re-aligns the final location of the test binary in the app folder when
building with make with it's location in the source tree.
For meson builds, the autotest app is different from the other apps in that
it needs a series of different test cases defined for it for use by "meson
test". Therefore, it does not get built as part of the main loop in the
app folder, but gets built separately at the end.

This is to logically group unit tests into their own folder,
separating them from "app" folder.
Hopefully this will make the unit test in DPDK more visible.
Following binaries moved to "test" folder:
cmdline-test
test-acl
test-pipeline
test <-- various DPDK unit tests

The tests are registered with their command name by adding a structure
to a list. The structure of each test was declared in each test file
and passed to the register macro.

Implement rte_memzone_free which, as its name implies, would free a
memzone.
Currently memzone are tracked in an array and cannot be free.
To be able to reuse the same array to track memzones, we have to
change how we keep track of reserved memzones.
With this patch, any memzone with addr NULL is not used, so we also need
to change how we look for the next memzone entry free.
Add new unit test for rte_memzone_free API.

Some unit test are not relevant anymore. It is the case of those malloc
UTs that checked corner cases when allocating MALLOC_MEMZONE_SIZE
chunks, and the case of those memzone UTs relaying of specific free
memsegs of rhte reserved memzone.
Other UTs just need to be update, for example, to calculate maximum free
block size available.

The DPDK dump functions are useful for remote debugging of an
applications. But when application runs as a daemon, stdout
is typically routed to /dev/null.
Instead change all these functions to take a stdio FILE * handle
instead. An application can then use open_memstream() to capture
the output.
