1. Add future::SelectAll::into_inner (rust-lang#2363) …

   When select all is not yet finished (for example, due to timeout),
   underlying futures may need to be extracted to be updated to construct
   a fresh select all.

3. Revert import changes in tests …

   After rust-lang#2216, these redundant imports are unneeded.
   This reverts almost all of rust-lang#2101.
   This also includes some minor cleanup of imports in tests.

6. Add .editorconfig …

   Add `.editorconfig` with sensible defaults.
   
   Many editors understand editorconfig, and the most important one
   here is IntelliJ IDEA which does not insert file trailing newline
   by default, but does it out of box this provided `.editorconfig`.

7. Allow calling UnboundedReceiver::try_next after None …

   Allow calling `UnboundedReceiver::try_next` and `Receiver::try_next`
   after `None`: do not panic.
   
   Not-panicking is equally safe, and does not have negative performance
   implication.
   
   It is irrelevant for `Stream` implementation to panic or not (because
   `Stream` behavior is unspecified after `None`), but panicking in
   `try_next` just complicates the interface: returned `Ok(None)` is
   reasonable assumption to have.
   
   Consider this use case: drain the queue on drop by performing
   app-specific cleanup of queued messages.
   
   The obvious implementation would be:
   
   ```
   impl Drop for MyReceiverWrapper {
       fn drop(&mut self) {
           while let Ok(Some(m)) self.try_next() {
               cleanup(m);
           }
       }
   }
   ```
   
   Without this change, I cannot even say for sure how this code need
   to be implemented to avoid panicking. E. g. is `is_closed` enough
   or some additional checks need to be performed?
