some conversion functions are not implemented in pa_converters.c

[PortAudio-admin]

Issue created by @RossBencina

Conversion functions in src/common/pa_converters.c copy audio data between PortAudio native buffers and host buffers.

https://www.assembla.com/code/portaudio/subversion/nodes/1930/portaudio/trunk/src/common/pa_converters.c

Some conversion functions are marked IMPLEMENT ME and do not pass any audio, some are marked REVIEW and may not currently work as expected.

All IMPLEMENT_ME functions are dithered variants of existing non-dither functions, so the non-dithered versions can be used as a starting point.

I havn't volunteered to fix this, but I have been working on some code to test the converters if anyone is interested please email me or the list.

This ticket will be greatly simplified once we decide on this one:

#112 -- require clipping for dithering sample conversion functions?

I implemented the Float32 to UInt8 conversions so that the loopback test would pass. The loopback test uses Float32 as its primary internal data type. Still more to go.
