Compile us to a C library for mobile integration

[lukechampine]

I've researched gomobile a bit more, and I think a mobile integration is totally doable.

gomobile has some restrictions around its bindings, like "Functions must return either no results, one result, or two results where the type of the second is the built-in 'error' type." Clearly there are lots of us functions that break this rule, so I was worried that building us on mobile was hopeless.

However, I was mistaken: the restrictions only apply to the package you want to bind, not all of the packages you depend on. Which means that you can write a "wrapper" package around us that calls all sorts of us functions, but whose API is compatible with gomobile.

So really the only thing required for an us mobile app is to write that wrapper. I don't think writing it will be hard at all; it's more a question of how to design the wrapper API. I assume the ideal wrapper will depend on what you want your app to do, so I probably won't include any such wrappers in the main us repo.

Anyway, I'll leave this open until there's been a successful demo of us on a phone. :)

sounds good, if I have some time this weekend I'll take a stab at it

I wrote some preliminary bindings here: https://github.com/lukechampine/us-bindings

I'll close this issue and move discussion to that repo.
