__inline__ - this is a proof of concept and will cover the raidframe
source as a whole over coming updates. Update namespace of function to
prefix with rf_ - comments again welcome.
* overall: rework the macros in rf_etimer.h and the resultant changes
to their use to count microseconds and not clock ticks. Restore the code
in rf_revent.c to a similar strcuture to before the previous commit,
and use the system timers to govern resource usage.
Tested with local i386/IDE and the reconstruction of a disk in my
array - performance has improved for reconstruction at no noticable
CPU cost.

based upon hardcoded CPU speed values and an assumtion that the number
of clock cycles was available. This is/was silly.
redone rf_GetNextReconEvent so that is now runs for 1/10th second
before sleeping for a short time (1/50th sec). Locally, this is using
about 25% of the CPU while rebuilding a disk in a four disk IDE RAID5
array. It was 22% of the way through when I last looked... much much
faster.
An even better way is sought - suggestions welcome. Lots of code that
the old routines relied on canm be harvested later.
Patches also being sent to Greg Oster @ NetBSD group.

* move composition og openmask in raidclose to before where it is
tested.

NetBSD. There is no reason to mess with these; they are just being
carried around as a reference at the moment.

Please note that you *must* follow the upgrade instructions at

before installing the new raidctl and new kernel using this code.
