Summary

This change is intended to address @glebius comments from the original D55663.
ip6_hdr_pseudo{} is referenced by certain OpenBSD OCF related components. I am
using aligned(4) and not packed as urged by the late Hans-Petter Selasky.
Use C99 types and style. We must eat the churn now cross-BSD compatibility
is "Fade to Black".

Put _Static_assert under #ifdef INVARIANTS to not disrupt regular compilation,
as this resides in a commonly included header file.

Compile tested for amd64 GENERIC.
The next Differential will contain the netipsec/xform_tcp.c refactoring to use ip6_hdr_pseudo{}.

The #ifdef INVARIANTS conditional for _Static_assert() is mostly a no-op, because GENERIC enables them via "include "std.debug"".
