Source/WebCore:

The new blend function added with r105403 takes unsigned as parameters therefore
we have to be careful to not overflow in case the to is less than from (animating
from 400 to 0 for example).

Source/WebCore:

BorderValue stores its width on a 12 bits unsigned. This patch
increase it to 27. The patch also modify the way to set the
width or to get it, we now use a unsigned rather than a short.

Reviewed by Dean Jackson.

Lots of places in the code had copies of the animation interpolation
logic "from + (to - from) * progress", in various forms.

Coalesce all these into calls to a few new inline functions in a new
AnimationUtilities.h header. Color and Length get their own blend fuctions
in their respective headers.

Covered by existing tests.
