Move the raid6 data processing routines into a standalone module

non-md drivers/modules.  This precludes a circular dependency of raid456
needing the async modules for data processing while those modules in
turn depend on raid456 for the base level synchronous raid6 routines.

To support this move:
1/ The exportable definitions in raid6.h move to include/linux/raid/pq.h

As raid*.h and md.h have been moved to drivers/md recently, pq.h
should probably live there as well.

+#define time_before(x, y) ((x) < (y))

This macro seems to have no users (and a strange name).
