[RFC] dmraid design 1.0.3

Attached is an RFC on the design of my dmraid tool/lib which read-only
supports (discover, activate, deactivate, display properties, ...)
various RAID devices (eg, ATARAID) in Linux 2.6 using the generic
device-mapper runtime.

Read-write support of such devices is subject to future extensions.

FYI: Implementation takes advantage of Søren Schmidt's work in freebsd
     and Carl-Daniel Hailfinger's on raiddetect; thanks guys :)

Any helpful comments appreciated. (please cc me, i'm not subscribed)

Code to comment on will follow ASAP.

Regards,
Heinz   -- The LVM Guy --
