* Some math functions become intrinsic in release mode, so we need to
convert all the math functions into SDL math functions, like we did
with the stdlib functions.
* Constant initializers of 8-bit values become calls to memset() in
release mode, but memset() itself is an intrinsic when explicitly
called. So we'll just explicitly call memset() in those cases.

Subject: Fusionsound audio driver
attached is a diff containing a audio driver for the FusionSound
library. This sound library is closely related to DirectFB and uses the
same transport (fusion) as DirectFB when running applications "remote",
i.e. over the network. As such, it natively redirects sound where
DirectFB redirects video. This may be handy for everyone using SDL over
DirectFB.
If a driver can definitely see available devices, it is chosen. Otherwise,
we'll take the first driver that initializes but saw no devices...this might
be because it can't enumerate them, or there really aren't any available.
This prevents the dsp driver from hogging control when there are no /dev/dsp*
nodes (for example, on a Linux box with ALSA and no OSS emulation).
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.

Subject: Fix to compile SDL-1.2 SVN on OS X Leopard
I found I needed to add a conditional check for Leopard to compile
cleanly on 1.2-SVN (20071114):
#include <AudioUnit/AudioUnit.h>
#ifdef AVAILABLE_MAC_OS_X_VERSION_10_5_AND_LATER
#include <AudioUnit/AUNTComponent.h>
#endif
where there is now just:
#include <AudioUnit/AudioUnit.h>

Subject: fix for audio dsp exit crash / various dfb issues
The current code will crash on exiting an application. The attached diff
fixes the issue.
(This already had a concession for devices opened via the 1.2 entry points,
I've changed it to respect the environment variable and do it for all devices
now.)
bitshift an Sint64, but it can't find this function since we don't use the
C runtime on Windows.
Division doesn't have this problem, though. Strange.
Thanks, Suzuki Masahiro.
