Pawel Jakub Dawidek fa4a1febf7 Add GEOM_MIRROR class which provide RAID1 functionality and has many useful
features. The gmirror(8) utility should be used for control of this class.
There is no manual page yet, but I'm working on it with keramida@.

Many useful tests provided by:	simon (thank you!)
Some ideas from:		scottl, simon, phk
