  Add support for the Nokia N-Gage (#5597)
  
  * Add initial support for the Nokia N-Gage
  
  * N-Gage: disable clipping for the time being, issue needs to be resolved later
  
  * Move va_copy definition to SDL_internal.h
  
  * Move stdlib.h include to SDL_config_ngage.h, much cleaner this way
  
  * Remove redundant include, add HAVE_STDLIB_H
  
  * Revert "N-Gage: disable clipping for the time being, issue needs to be resolved later"
  
  This reverts commit 4f5f0fc36cc7f34fad05e45671dfa7b8dc32fd51.
  
  * N-Gage: fix clipping issue by providing proper math functions
