Problem with callbacks

[M-HT]

Here's an example of problematic scenario with callbacks:

• SDL_OpenAudio is called with callback which uses AddCallback to add a new callback
• inside the callback function the code calls qsort which uses AddSharedCallback to add a new shared callback and then uses FreeCallback to remove the shared callback
• since qsort callback is shared, it uses the same emu as callback from SDL_OpenAudio, so removing the shared callback also removes the callback from SDL_OpenAudio
• further calls to SDL_OpenAudio callback print the text Warning, Callback not found?! instead of calling the callback

The FreeCallback on a Shared callback should not free the emu. I'll check that, thanks!

EDIT Oh, I see, the Callback itself is deleted, not the emu!

Commit 0398803 should have fixed it.

I tested it and the problem is fixed (at least in described scenario).

Nice, thanks for testing.
