Add rav1e to package managers

[EwoutH]

Not directly related to the codebase, but it would be very useful to have rav1e available in the most used package managers. These for example:

• APT (Debian / Ubuntu)
• Homebrew (macOS)
• Chocolatey (Windows)

@lu-zero Homebrew requires at least one tagged version. Is there a release that can be tagged as 0.0.1? Or maybe we can do weekly releases untill we tag things as stable, like rav1e-2019.01.28.

[lu-zero]

I'm fine with the weekly tag approach, but I'd like to have everybody ack it.

[lu-zero]

(once we have a tag we could also produce crav1e builds/packages)

Here a prerelease so we can see what is missing packaging-wise.

I created https://bugs.debian.org/920842 asking for a Debian package. Tagged releases will make it more likely. :)

cc @infinity0 Rust Debian packager and @cuviper Rust Fedora packager

Are you interested only in select few repositories or any? For example:

@jbeich The more the merrier :).

For CI the Ubuntu LTS versions (14.04, 16.04 and 18.04) and Debian Stable are the most important.

For general use Manjaro, Mint, MX Linux, elementary and Fedora would also be nice.

cc @ignatenkobrain for Fedora too.

There are few crates we don't have packaged yet. But otherwise it should be doable.

I'll look at it after FOSDEM

[tdaede]

Cool. Many of us are at FOSDEM too :)

Maybe at least publish pre-built executables for various linuxes to Github releases?

Having one for the latest Ubuntu LTS would be nice as it's pretty common
