Math: ability to construct vectors and matrices from sized arrays.
...
Same as done for Containers::StaticArray some time ago. Since it's not a
potentially dangerous operation, it's not made as an overload of the
from() function, but instead a regular constructor. It's however kept
explicit for now, even though it eventually might not need to be -- I'm
not sure about potential consequences yet.

Also adjusting two tests which were calling rotation() on matrices that

Math: be reasonable, <utility> is not needed for std::declval.
...
Despite what the standard tries to say. I bet a large portion of
<type_traits> is impossible to implement without it, which is why all
STL implementations define it there already.

Math: stop wasting time with the explicit Corrade:: prefix.
...
I did this back in 2010 because it "felt like the right thing to do",
given that all of Magnum depended on Math and not vice versa. But,
strictly speaking, Math already uses typedefs from Magnum/Types.h so why
it couldn't also bring in the Corrade namespace, and the
Debug/Warning/Error names too. Having to type out Corrade:: in all these
was really just a waste of time, weird inconsistency in docs and an
extra roadblock for whoever might want to contribute anything there.

Math: change all assertions to debug-only.
...
The perf cost is just too great for these to be enabled always. The only
place where the assertions are kept always is in the batch APIs -- there
it's assumed the function is called on large enough data to offset this
overhead, plus since it's often dealing with large blocks of data the
memory safety is more important than various FP drifts which were the
usual case why other assertions were firing.

Math: redo Matrix4::normalMatrix() as an inverse transpose.
...
The article this API was originally based on assumes a scenario which
just *isn't* matching usual practices here, giving wrong results. Too
bad I didn't spend more time questioning the proof there and just
blindly assumed it's correct because everyone said so.
Won't be typing all that reasoning again in the commit message, see the
changelog entry and the comment in the test for details.

The old one is deprecated, and will be removed in a future release.
Unfortunately, to avoid deprecation warnings, all use of NoInit in the
Math library temporarily have to be Magnum::NoInit This will be cleaned
up when the deprecated alias is removed.
