[Bug 1675770] Re: lvcreate cannot use more than 8 stripes

[ChristianEhrhardt]

I provided a fix to test in the following ppa:
https://launchpad.net/~ci-train-ppa-service/+archive/ubuntu/2646

In my testing that worked up to 128 stripes again.

Subscribing sponsors as I can't upload LVM, could you take a look at it.
There are a few burnt version numbers involved up to 
 https://launchpad.net/ubuntu/+source/lvm2/2.02.167-1ubuntu4 If I checked correctly.
None of these made it or - as it seems - are going to do so.
So I'm jumping at -ubuntu5 and kill the failed history.

For your convenience as it is a bileto ticket, so
- diff is at: 
- sponsoring can be done via publish on: https://bileto.ubuntu.com/#/ticket/2646
