Recent versions of doxygen (1.9.4 and newer) complain about
documented return types for functions that don't return anything.
This patch removes these return types to fix build errors similar
to this one:
[..]

Start a new release cycle with empty release notes.
The ABI version becomes 23.0.
The map files are updated to the new ABI major number (23).
The ABI exceptions are dropped and CI ABI checks are disabled because
compatibility is not preserved.
Special handling of removed drivers is also dropped in check-abi.sh and
a note has been added in libabigail.abignore as a reminder.

Merge CRC32 hash calculation public API implementation for x86 and Arm.
Select the best available CRC32 algorithm when unsupported algorithm
on a given CPU architecture is requested by an application.
Previously, if an application directly includes `rte_crc_arm64.h`
without including `rte_hash_crc.h` it will fail to compile.

These functions all behave like libc free() and do
nothing if handed a NULL pointer. The code is already doing
this, this patch just documents the behavior.

This patch fixes various issues:
- replace _mm512_set_epi8 with _mm512_set_epi32 due to the lack
of support by some compilers (at least, gcc 8),
- check if AVX512F is supported along with GFNI, this is done if the code
is built on a platform that supports GFNI, but does not support AVX512,
- fix compilation problems on 32bit arch due to lack of support for
_mm_extract_epi64() by implementing XOR folding with
_mm_extract_epi32() on 32-bit arch,

Currently there are some public headers that include 'sys/queue.h', which
is not POSIX, but usually provided by the Linux/BSD system library.
(Not in POSIX.1, POSIX.1-2001, or POSIX.1-2008. Present on the BSDs.)
The file is missing on Windows. During the Windows build, DPDK uses a
bundled copy, so building a DPDK library works fine. But when OVS or other
applications use DPDK as a library, because some DPDK public headers
include 'sys/queue.h', on Windows, it triggers an error due to no such
file.
One solution is to install the 'lib/eal/windows/include/sys/queue.h' into
Windows environment, such as [1]. However, this means DPDK exports the
functionalities of 'sys/queue.h' into the environment, which might cause
symbols, macros, headers clashing with other applications.
The patch fixes it by removing the "#include <sys/queue.h>" from
DPDK public headers, so programs including DPDK headers don't depend
on the system to provide 'sys/queue.h'. When these public headers use
macros such as TAILQ_xxx, we replace it by the ones with RTE_ prefix.
For Windows, we copy the definitions from <sys/queue.h> to rte_os.h
in Windows EAL. Note that these RTE_ macros are compatible with
<sys/queue.h>, both at the level of API (to use with <sys/queue.h>
macros in C files) and ABI (to avoid breaking it).
Additionally, the TAILQ_FOREACH_SAFE is not part of <sys/queue.h>,
the patch replaces it with RTE_TAILQ_FOREACH_SAFE.

rte_thash_adjust_tuple() uses random to generate a new subtuple if
fn() callback reports about collision. In some cases random changes
the subtuple in a way that after complementary bits are applied the
original tuple is obtained. This patch replaces random with subtuple
increment.

There is no reason for the DPDK libraries to all have 'librte_' prefix on
the directory names. This prefix makes the directory names longer and also
makes it awkward to add features referring to individual libraries in the
build - should the lib names be specified with or without the prefix.
Therefore, we can just remove the library prefix and use the library's
unique name as the directory name, i.e. 'eal' rather than 'librte_eal'
