Perl 5.20 upgrade

[Jitka Plesnikova]

Hello,

We have acquired `f22-perl' build-root. Perl 5.20 mass rebuild can start.
You can be notified via mail about commits and builds in next days.

Please do not build anything into `f22-perl'. Boot-strapping core modules is
very peculiar. I also track all changes. You can do your upgrades into rawhide
freely in parallel.

You can check status on Perl 5.20 change page 
<https://fedoraproject.org/wiki/Changes/perl5.20>
