[Mageia-dev] freeze push: vowpal-wabbit 7.2

[Pierre-Malo Deniélou]

Vowpal-wabbit is a machine learning computational tool. We currently 
have 7.1. Nothing depends on it, and it was not in Mageia 2.

I don't have a changelog (it's a huge git commit dump) to show, but it 
works and allows to drop the patches we used and were upstreamed.

Thanks,
