Build the SDL library as a shared object on Android, so it will work correctly with SDL_image and SDL_ttf.

I think this also fixes some of the red/blue channel swap bugs reported on iPhone.

There was a dummy renderer left in there which was overriding the OpenGL ES renderer.

Minor configuration changes to smooth the build process, make it work on mac.

FIXME: Still need to pass some arguments - can we get them from the Java class?

uses variable-size enums yet the output is to use 32-bit enums

(1) SDL_atomic dummy version in SDL 1.3 is not used.
Because src/atomic/dummy/*.c are not used.

(2) Typo in src/joystick/bsd/SDL_sysjoystick.c.

Thanks,

Renamed SDL_TextureScaleMode to SDL_ScaleMode

Fixed building on Mac OS X 10.5
