Now all sounds that are not mono but have 3D checked automatically get reduced to mono during BGE conversion time.
Also removed the now unneeded function sound_get_channels and added a missing header file to audaspace's CMakeLists.txt.
Mixdown functionality.
* Mixdown possible via libsndfile and ffmpeg!
* Fixed some ffmpeg deprecation warnings
* Mixdown UI only shows working Container, Codec and Format combinations!
* Minor bugs and warnings fixed
Implementation of Julius O. Smith's resampling algorithm for high quality audio resampling.
The filter currently is a sinc filter with a 0.9 cutt-off and windowed by a kaiser window (beta = 10).
Also includes minor changes in the linear resampler.
Main: Complete rewrite of the sequencer related audio code to support 3D Audio objects later and especially adressing the animation system problems (see mailing list if interested).
Note: Animation is not working yet, so with this commit volume animation doesn't work anymore, that's the next step.
Minor things:
* Changed AUD_Reference behaviour a little to be more usage safe.
* Fixed bug in AUD_I3DHandle: Missing virtual destructor
* Fixed enmus in AUD_Space.h
* Fixed a warning in rna_scene.c
* Removed an unneeded call in rna_sound.c
blender_add_lib now takes a separate include argument to suppress warnings in system includes (mostly ffmpeg & python).
also only build wm_apple.c on apple+carbon configuration.
Added central compatibility header file, which enables blender to compile
against very old ffmpeg versions as well as very new versions using the
*NEW* API. (Old API functions are simulated using macros and inline functions)
Added a whole lot of additional checks, tested against 6 different versions
down the timeline, hopefully, now finally all is well.
globbing vs explicit is discussed here.

Practical implications are:
- developers need to keep CMakeLists.txt files up to date.
- Users wont get strange linking errors if they build after a file is added, since CMake detects CMakeLists.txt is modified and automatically reconfigure.
- transform default scale was too hight, calls to random were inconsistant. (fault of own modif's)
- cmake openal include was added twice on recent commit.
