Various fixups:

 feeder.h:
 feeder.c:
	- Implement scoring mechanisme to select best format for conversion.
	  This is actually part of newer format chaining procedures which
	  will be commited someday. Confusion during chaining process solved
	  by this scoring since it will try to reduce list of from/to formats
	  to a single, best format.

channel.c:
	- Simplify feeder building process since we have smarter format
	  chaining.

feeder_fmt.c:
	- Add few more sign conversion feeders for 24 and 32 bit format.

feeder_rate.c:
	- Force buffer / bytes allignment. Unaligned buffer may cause
	  panics during recording on pure 32bit sample format if it
	  involves feeder_rate as part of feeders chain.
	  Tested on: ATI IXP, force 32bit recording.
