Pawel Jakub Dawidek f5a2f7feac Implement new reading algorithm, which will use parity component for reading 
as well, even if device is in complete state.
I observe 40% of speed-up with this option for random read operations,
but slowdown for sequential reads.
Basically, without this option reading from a RAID3 device built from 5
components (c0-c4) looks like this:

	Request no.	Used components
	1		c0+c1+c2+c3
	2		c0+c1+c2+c3
	3		c0+c1+c2+c3

With the new feature:

	Request no.	Used components
	1		c0+c1+c2+c3
	2		(c1^c2^c3^c4)+c1+c2+c3
	3		c0+(c0^c2^c3^c4)+c2+c3
	4		c0+c1+(c0^c1^c3^c4)+c3
	5		c0+c1+c2+(c0^c1^c2^c4)
	6		c0+c1+c2+c3
	[...]
