ab04a1915e [build] Fix a pile of gcc 10 issues
gcc got stricter about array accesses, complicating progs macros, and
much better at detecting buffer overflows.

62f3e1f428 [util] Calculate quaternion to rotate between two vectors
The calculation fails (produces NaN) if the vectors are anti-parallel,
but works for all other combinations. I came up with this implementation
when I discovered Unity's Quaternion.FromToRotation could did not work
with very small angles. This implementation will produce a usable
quaternion below 0.00255 degrees (though it will be slightly larger than
unit). Unity's failed such that I could see KSP's skybox snap while it
rotated around my test vessel.

f58c2fef5a Switch QF's quaterions from wxyz to xyzw.
After messing with SIMD stuff for a little, I think I now understand why
the industry went with xyzw instead of the mathematical wxyz. Anyway, this
will make for less pain in the future (assuming I got everything).

34bcf7faab Do a pure/const/noreturn/format attribute pass.
I always wanted these, but as gcc now provides warnings for functions that
could do with such attributes, finding all the functions is much easier.

f0dc995c67 Handle c99 inline vs gnu89 inline.
The meaning of "extern inline" and "inline" swaps between the two, and
gcc-5 uses c99 inline.

54b4d589aa Split up mathlib.h into several smaller headers.
This should make maintaining them a little easier.

The copyright block in most of the new headers (execpt vector.h) reflect
when the functions in the relevant header were first created.
