Don't make some AudioOutput members fully virtual.
Default implementation being that they return false



commit cf944522addf2a78d087d26b8a841eaf14040787

Add libmyth/audio unit tests
Currently only test float format conversion routines.



commit 354412ccc4ac0f7475ab2d9eb114a8021b664c31

Adjustment to float conversion routines
We originally made the conversion routines use a symmetrical range of -32767 - 32767 which always cause -32768 to be clipped to -1.0. However, SSE clipping code changed that behaviour making the C-code conversion routine behave differently to SSE code. Converting S16 samples wouldn't always be in the -1.0 .. 1.0 range causing clipping later on.

Also, due to the forthcoming change to the transcoder, S16 -> Float -> S16 needed to be lossless which the previous code didn't abide to.

Make floating point conversion routines work even when not 16 bytes aligned.
This simply uses C-code instead of SSE code if neither of the destination nor origin are 16-bytes aligned
