[RFC 0/3] eal: make unaligned types really unaligned

[Stephen Hemminger]

UBSAN reported issues in the tests added by the RTE_PTR_ADD/SUB patch.
The root cause is that unaligned_uint16_t, unaligned_uint32_t and
unaligned_uint64_t are not really unaligned on x86; they only get an
alignment of 1 when RTE_ARCH_STRICT_ALIGN is set.

Once that is fixed, RTE_ARCH_STRICT_ALIGN is no longer needed and can
be removed along with its last user in mlx5.
