Heinz Mauelshagen f2d7a48418 lvconvert: add raid1 <-> raid4 conversion ...

In addition to the already supported conversion between 2-legged
raid1 and raid5, raid1 and raid4 can be also converted into each
other with 2 legs (raid4/5 are limited to map a 2-legged raid1).

This patch supports the missing raid4 conversion in the sequence
linear -> 2-legged raid1 -> raid4/5, then restripe to more than one
data stripes for performance and resilience reasons and optionally
convert to striped/raid0.

The other conversion sequence is also possible by converting N-way
striped/raid0 to raid4/5, then restripe to 2 legs followed by a
conversion to raid1 and optionally to linear (loosing all resilience).
