[PATCH v8 00/21] remove use of VLAs for Windows

[Andre Muezerie]

From: Andre Muezerie <andremue at ntdev.microsoft.com>

As per guidance technical board meeting 2024/04/17. This series
removes the use of VLAs from code built for Windows for all 3
toolchains. If there are additional opportunities to convert VLAs
to regular C arrays please provide the details for incorporation
into the series.

MSVC does not support VLAs, replace VLAs with standard C arrays
or alloca(). alloca() is available for all toolchain/platform
combinations officially supported by DPDK.

v8:
 * rebase
 * reduce scope for disabling error "-Warray-bounds=" to only
   the place that needs it
 * remove parentesis around numbers from defines in test_bitset.c

v7:
 * remove use of VLA from new file which sneaked in during review

v6:
 * remove use of VLA from new test code added recently
 * fix title for patch 08/20

v5:
 * add patches for net/ice, net/ixgbe and gro
   from Konstantin Ananyev from
https://patchwork.dpdk.org/project/dpdk/list/?series=31972&archive=both&state=*
 * address debug_autotest ASan failure
 * address array-bound error in bitset_autotest with gcc-13

v4:
 * rebase and adapt for changes made in main since v3 was sent
 * use fixed maximum array size instead of VLA when doable

v3:
 * address checkpatch/check git log warnings (minor typos)

v2:
 * replace patches for ethdev, hash, rcu and include new
   patches for eal from Konstantin Ananyev
   from https://patchwork.dpdk.org/project/dpdk/list/?series=31781
