This is inspired by bug reported here [1]. Even though Eric suggested
calling this Linux syscall when building without gnutls [2] I've decided
to not implement it. Firstly, we build with gnuls everywhere (even
Windows), secondly I see no appealing reason to special case Linux -
/dev/urandom is good for both Linux and FreeBSD.
Once these are merged I'm probably going to send patch set that makes
gnutls mandatory. I'm tired of all those WITH_GNUTLS if-defs (esp. in
function arguments). But that is orthogonal to what I'm solving here.
Also, I'm not quite sure this is a release material, so I'm fine with
merging this after the release.

I'm not sure if we're getting a CVE assigned for this (if Red Hat
security gets back to me on that question, and says a CVE is warranted,
then maybe it still is a candidate for this release). But if a CVE is
assigned, the fact that this issue has been public since 2014 means that
one more broken release added to years of neglect regarding the issue
won't hurt much.
