Description

It looks like the change from CLJS-615 requires the addition of something like this prior to using any of the dependency machinery:

(swap! env/*compiler* assoc :js-dependency-index (cljsc/js-dependency-index opts))

That the dependency index is now in the compiler environment isn't a problem (on the contrary), but cljs.env/default-compiler-env is there for exactly this sort of thing: the environment that fn returns should have :js-dependency-index added already. This would necessitate pulling all of the JS dependency resolution machinery up into cljs.env (or perhaps another namespace, cljs.js-deps?), but would eliminate the user-facing complication of getting a useful compiler environment with a side benefit of getting all the JavaScript dependency stuffs out of cljs.closure and into a home of their own.

I'm mucking with this in conjunction w/ CLJS-656; shouldn't be difficult to do afterwards.

Interested?

Attached patch refactors goog-style JS dependency stuff into cljs.js-deps, and changes cljs.env/default-compiler-env to populate :js-dependency-index based on the provided set of options.

I didn't move the externs stuff, seemed like it should stay in cljs.closure.

Note that this doesn't change the fact that CLJS compiler API consumers will need to change: cljs.env/default-compiler-env now takes a map argument of options, which needs to be provided if such consumers need to have their e.g. :libs, :foreign-libs options picked up. The advantage is default-compiler-env again does the job it's intended to do. The refactoring / slimming of cljs.closure is a nice side effect, tho.

I'm ok with pulling this stuff into it's own namespace.
