Ed Schouten 7c99b6764e Add static/const keywords to the arrays.
This theoretically allows a compiler to optimize (parts of) the array
away if unused.

While there, make the array size implicit and use a _Static_assert() to
ensure that the definition matches up with the number of elements in the
list.
