I currently have a 3500 line diff in my tree that completely rewrites
softraid metadata handling.  The idea is that when this goes in we can
start adding foreign raid formats as sub-drivers to softraid.  This also
fixes issues of power failures and crashes where the checksums are no
longer correct.  To top it all the code is far cleaner now.  I am about
95% done so hang in there.

When this change goes in old softraid metadata formats will no longer
work!  So now is a good time to get dumps going.  I am _not_ planning on
adding a metadata driver for the previous versions.

I will be soliciting tests soonish to get the diff production ready so
that we can officially support RAID 0 and CRYPTO for the 4.4 release.
RAID 1 will continue to be experimental until I get a chance to work out
the rebuild mechanics (hi henning!!).
