futures: lentify (#413)
sometimes avoid copies when reading from `Future`

Introduce `chronos/futures` (#405)
* move `Future[T]` into its own module along with some basic accessors
* mark all fields internal, exposing only read-only versions under the
old names
* introduce `init`/`completed`/etc as a way of creating a future (vs
newFuture)
* introduce `LocationKind` for `SrcLoc` access
* don't expose `FutureList` unless future tracking is enabled
* introduce `chronosStrictFutureAccess` which controls a number of
additional `Defect` being raised when accessing Future fields in the
wrong state - this will become true in a future version

In this version, `Future[T]` backwards compatibility code remains in
`asyncfutures2` meaning that if only `chronos/futures` is imported, only
"new" API is available.

This branch is a refinement / less invasive / minimal version of
https://github.com/status-im/nim-chronos/pull/373.
