* rf_reconstruct.c: adopt nilkas' suggestion regard statics and
__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.
