VS2005 tweaks (thanks, Ozkan!).

Browse Source 
Fixes Bugzilla #2895.

His notes:

The following trivial changes make SDL2 tree (mostly) compatible with Visual
Studio 2005:

* SDL_stdlib.c: Similar to VS2010 and newer, VS2005 also generates memcpy(),
  (it also generates memset(), see below), so propagate the #if condition to
  cover VS2005.

* SDL_pixels.c (SDL_CalculateGammaRamp): VS2005 generates a memset() call for
  gamma==0 case, so replace the if loop with SDL_memset().

* SDL_windowsvideo.h: Include msctf.h only with VS2008 and newer, otherwise
  include SDL_msctf.h

* SDL_windowskeyboard.c: Adjust the #ifdefs so that SDL_msctf.h inclusion is
  always recognized correctly.
