add IntoFuture trait and support for await

[seanmonstar]

The async-await RFC mentions being able to await anything implementing IntoFuture. Somewhere along the way, it was left out.

(My machine dies trying to compile rustc, so I'll be needing CI to tell me if I goofed a small thing. And I can add a tracking issue if accepted.)

2019-10-09T17:45:33.5442692Z Description  : Get sources from a repository. Supports Git, TfsVC, and SVN repositories.

I'm a bot! I can only do what humans tell me to, so if this was not helpful or you have suggestions for improvements, please ping or otherwise contact @TimNN. (Feature Requests)

[nikomatsakis]

The code generally looks good to me -- though I feel like the test ought not to be passing. Let's see what travis says.

Anyway, the other question is whether we want to enable this. It'd be good to capture some of the motivation. The main thing I've heard (which I find persuasive) came from the async-finalizers blog post by @yoshuawuyts. The main reason I've heard for removing IntoFuture was basically "YAGNI" -- not sure if there were more motivations than that? (Maybe @withoutboats remembers?)

[nikomatsakis]

We should file a tracking issue, but let's hold off just a bit.

[tmandry]

There should be a tracking issue before this gets merged, though, I think.

[cramertj]

I don't think it was forgotten about-- IntoFuture was intentionally removed from futures-rs a while back because the only things left that implemented it were tuple types. I'm not opposed to this PR at all; I don't know of any serious downsides to providing this functionality, aside from potentially yet another layer of indirection for error messages. However, I am curious to see what use-cases you have in mind for it!

[nikomatsakis]

@cramertj did you see the async-finalizers (since renamed to async-builders, I think) blog post I was referring to? That's at least one use case.

(I'd like to know if @seanmonstar had another use case in mind, though!)

[seanmonstar]

Yes, I've long had various builders in reqwest and hyper that I've previously felt would be nice if they could easily become futures, but they themselves aren't futures.

(My office internet is flaking hard, so might take a bit to update the PR.)
