Fixed Visual C++ release build for Visual C++ 2005

Browse source 
* Some math functions become intrinsic in release mode, so we need to
  convert all the math functions into SDL math functions, like we did
  with the stdlib functions.
* Constant initializers of 8-bit values become calls to memset() in
  release mode, but memset() itself is an intrinsic when explicitly
  called.  So we'll just explicitly call memset() in those cases.
