Use CI to build release binaries

[squeek502]

Currently only have a few precompiled binaries for Luvi's newer releases. We've been meaning to set this up for a while but never gotten around to it. Example of when release deploying was added to luv via travis: luvit/luv@6b901a2

Related issues: #187, #181

Here's what we had in v2.7.6: https://github.com/luvit/luvi/releases/tag/v2.7.6

• Windows Use appveyor to build/release Windows binaries #201
• Linux Use travis to build/release Linux binaries  #202
  • i686
  • x86_64
• Mac/Darwin active travis auto publish release #203
• ARM
  • aarch64 / arm64
  • armv7
  • armv6
• FreeBSD

Yes, this would be great if it could be automated. I think travis now has OSX guests and we have appveyor for windows, so it should be possible for most of these.

I was building freebsd and linux-686 in virtualbox images on my workstation, but I don't think those are as needed as others if it proves to be a problem.

Enough if win-x64,Mac-x64,Linux-x64 auto github-release for ci.Others are optional

[creationix]

Sure, that would be the bare minimum. Next important on the list I think would be arm32 and arm64 variants. Those platforms are getting more and more popular.

That means arm platform need manual release, I do not have news about arm free CI platform

[creationix]

Sometimes you can build them inside docker or chroots using qemu-user-static to emulate arm CPUs

[squeek502]

I'm going to start working on the Windows targets now. Will do the Linux/Mac ones after that.

For Linux:

• Got something mostly working for x86_64 and i686 using travis, docker, and holy-build-box (master...squeek502:master / example release) but the resulting binaries are gigantic--need to look into why that is. EDIT: It's debug info.
  EDIT#2: Fixed and made a PR: Use travis to build/release Linux binaries  #202

For Mac:

• Right now we don't have Mac CI turned on at all, and I don't have a Mac to do any testing, so will probably need some help with this when I get around to it

For ARM:

• Funnily enough, the top google result for "travis arm" (for me) is an old article about getting Travis to cross-compile Luvit (1.0) for ARM: https://www.tomaz.me/2013/12/02/running-travis-ci-tests-on-arm.html
• It might be easier now to use Docker; more possible solutions here: Support Android / Arm travis-ci/travis-ci#3376

For FreeBSD:

• I know sourcehut.org/sr.ht offers FreeBSD CI and it should be possible to integrate that with Github in some way (seen it mentioned that it's possible before). EDIT: More info: https://man.sr.ht/tutorials/builds.sr.ht/github-integration.md

@squeek502 I'll continue to finish Mac base your code.
