6989f94d6e Get rid of InsecureRand and use equivalent FastRandomContext
Also extend FastRandomContext to be compatible to existing uses, especially
with std::random_shuffle

Make sure that GetRandomBytes never fails
We're using GetRandomBytes in several contexts where it's either
unwieldy to return an error, or an error would mean a fatal exception
anyhow.

@gmaxwell checked OpenSSL a while ago and discovered that it never
actually fails, but it can't hurt to be a bit paranoid here.
