trivial: make StmtStream Send

[agalakhov]

StmtStream was not Send due to pointer in PhantomData. This pointer makes no sense since PhantomData is already zero-sized.

This is likely to fix #103.

Technically this is related to dropchk, which is why a &'static R would be more appropriate.

I'm at this time not planning to cut another 0.3 release,
since I'd like to get a preview of 0.4 (async/await) ready in a few weeks,
with the goal of addressing most painpoints.

Unfortunately &'static R won't work since it is not Send if R is not Sync. Only non-pointer type will do.
Another possible solution would be unsafe impl Send.

Yeah right, if I come accross something like this it on 0.4, which is substantially different, we likely just use PhantomData<R>. On a more general note: Let me know in case you need this in 0.3 or if you want to wait a little longer until I get that ready.
