Split deadlock

Is it really an issue of split? The example in the discussion uses BiLock instead of split.

They are the same, generally.

I don't think that it's a solvable problem with our current traits.

[Berrysoft]

We need to solve the split-related problems before 0.19 being released.

• AsyncRead + AsyncWrite could not be splitted easily with BiLock.
• The compat AsyncStream needs the inner stream's shared reference to impl AsyncRead + AsyncWrite for safety.
• TlsStream doesn't impl AsyncRead / AsyncWrite for its shared reference.

The problems above have been solved.
