Move ChaChaRng and Hc128Rng to their own crates

[vks]

This leaves rand::prng as a module only containing deprecated code. In principle it could be removed/hidden, but we still want to have the PRNG comparison somewhere.

[vks]

This fixes #431 (only what is said in the title, not the whole list in the issue).

Thanks @vks.

The CI seems to be complaining about broken links in the documentation.

Could you rebase after #611 please with the relevant changes?

[dhardy]

Okay @vks could you please update in line with #611? In particular, the authors line (ChaCha should list both; Hc128 can just list the Rand project devs). Also, the LICENSE-MIT files.

[vks]

I'll have a look, but presumably not before next week, when I'm back from vacation.

@dhardy I think I addressed all your concerns. I'll squash after review.

[dhardy]

Thanks @vks, mostly looks good.

I see you updated script.sh but this is only for the Trust cross tests. You should update .travis.yml and appveyor.yml too.

[vks]

I don't know what is going on with those MIPS and ARMv7 failures. The rest should be fine now.

[dhardy]

Me neither. On both runners the ChaCha crate passes but the HC128 one fails. There's very little difference between the Cargo.toml or lib files; the only significant thing I see is a build script for ChaCha.

You can just comment out the hc128 cross-tests and merge if you like; everything else looks good.
