Expose unsafe_unwrap
...
This at least ensures we don't have to needlessly leak generators in the
tests, and covers similar use cases for consumers of libfringe.

Don't use unsafe for the forget_yielded test
...
Now that the Send bound is gone, we can simply use a Cell instead of a
raw pointer.

Don't implement Send at all
...
On hosted platforms, libstd allows safely borrowing values from TLS with
'thread lifetime and without a Sync bound. As a result, we can't
guarantee that sending a generator across threads won't create dangling
references or data races. In freestanding environments, the notion of
thread-safety is likely to be defined by the consumer of libfringe,
so our Send bounds and implementation are unlikely to be meaningful
anyway.

Make the passed Yielder borrow immutable [breaking-change]
...
Yielder::suspend only requires an immutable reference, and allowing
mem::replace on the yielder isn't very useful.

Ensure that the closure outlives the generator [breaking-change]
...
Previously, it was possible to cause unsafety by having the closure
refer to values with lifetimes that weren't enclosed by the generator's
lifetime.

Rename Yielder::generate to Yielder::suspend.
...
This makes more sense, because "generate" implies *running*
a generator, not *returning* from a generator. That name was
a vestige of the time when libfringe only really provided a .next()
implementation, which made marginally more sense together with
.generate(), but it doesn't anymore when we have .resume().
