To reduce cast and braces burden, add permanent array-of-u16 aliases with the same size as the `union ice_prot_hdr` itself via anonymous unions to the actual struct declaration, and just access them directly. This: - removes the need to cast the union to u16[] and then dereference it each time -> reduces the horizon for potential bugs; - improves -Warray-bounds coverage -- the array size is now known at compilation time; - addresses cppcheck complaints.

Move all the repetitive constructions into two macros and let them do the name and type expansions. Linewrap removal is yet another positive side effect.
