  Move location of __rte_aligned(a) to new conventional location. The new
placement between {struct,union} and the tag allows the desired
alignment to be imparted on the type regardless of the toolchain being
used for both C and C++. Additionally, it avoids confusion by Doxygen
when generating documentation.

pad1/2/3/4/5 should be replaced by RTE_CACHE_GUARD, if that is their purpose.

@David: You might want to change this in a future patch.

Aligning a pointer to the size of a pointer is superfluous, unless the structure is packed.

@Radu, @Akhil: You might want to remove these in a future patch.

thanks morten. if the maintainers reply to acknowledge i will update the
series with your recommended feedback.

i noticed a couple of these as well when making the conversion but
resist the urge to change them to avoid confusion/review overhead.
