`extern crate alloc` pulled in without alloc feature

1

The use of `extern crate alloc` is unconditional, which is odd given there is an alloc feature. My expectation would be that * everything that doesn't even depend on alloc...

The `stream::pending` module is only exported for the "unstable" feature: https://github.com/async-rs/async-std/blob/4d9499c27751aa47bcd1c8f1cb0e56ee9a2e338b/src/stream/mod.rs#L328, but these items are not documented to require the feature in the docs like they are for other unstable...

Consider making waker_set its own crate

async_std::sync::Mutex is too heavy
