uhypsq calculates the hypotenuse using unsigned multiplication. This is permissible since for arbitrary int32s a and b, the following holds in two's complement arithmetic: (int32_t)((uint32_t)a * b) == (int32_t)((int64_t)a * b) ("Signed and unsigned multiplication is the same on the bit level.") This fixes various overflows where wall lengths for walls of length > 46340 are calculated, but does not rid us of other overflows in the same vein (usually dot products between vectors where one point is a wall vertex and the other a position in a sector). git-svn-id: https://svn.eduke32.com/eduke32@2791 1a8010ca-5511-0410-912e-c29ae57300e0
