Fixed SDL 1.2 compatibility problem.
The API specifies that SDL_OpenAudio() will fill out the 'desired' audio spec
with the correct samples and size set by the driver. This value is important
since it may be used by applications that size audio buffers, etc.
However, we want to allow advanced applications to call SDL_OpenAudioDevice()
which gets passed a const 'desired' parameter, and have the correct data filled
into the 'obtained' parameter, possibly allowing or not allowing format changes.
So... 'obtained' becomes the audio format the user callback is expected to use,
and we add flags to allow the application to specify which format changes are
allowed.
Note: We really need to add a way to query the 'obtained' audio spec.

TestiPhoneOS.xcodeproj contains targets to compile many of the SDL test programs for iPhone OS. Most of these test programs work fine, with the following exceptions: testalpha: Program crashes. Problem appears to effect Mac OS X as well. testhread: SIGTERM kills the process immediately without executing the 'kill' function. The posix standard says this shouldn't happen. Apple seems intent on having iPhone apps exit promptly when the user requests it, so maybe that's why(?) testlock: Locks appear to work, but there doesn't appear to be a simple way to send the process SIGINT. testpalette: "SDL error: blitting boat: Blit combination not supported." Happens on Mac OS X as well. testsprite2: SDL_CreateTextureFromSurface requests an ARGB pixel format, but iPhone's SDL video driver only supports ABGR. testwin: Behaves as it does under Mac OS X ... not sure if that is correctly or not. threadwin: Works if -threaded is not on. Otherwise it doesn't work, but this is true under Mac OS X as well.
