PSL 6.4.2

This release fixes two Windows bugs that made a failed TLS handshake, and a peek on a reset TCP connection, spin at full CPU until cancelled instead of failing. Upgrading is recommended if you make or accept TLS connections, or peek TCP connections, on Windows.

Fixes

• TLS: On Windows, a client or server handshake now fails with TLS\Exception\HandshakeFailedException when one of its steps fails, for example because the peer closed or reset the connection. PHP on Windows reports such a step as still in progress, because it tells a waiting step from a failed one by an errno that Winsock never resets, so the handshake retried the socket at full CPU until its cancellation token ended it: forever with the default token, and for 10 seconds per connection with the default TLS\Listener deadline. HTTP\Client and SMTP make their TLS connections through TLS\Connector, so they are fixed too. (by @azjezz)
• TCP: On Windows, a peek on a connection that the peer has reset now throws IO\Exception\RuntimeException instead of spinning at full CPU until its cancellation token ends it. Such a connection stays readable while every peek fails, and it keeps its peer's name, so it did not look failed and the peek waited for it again. (by @azjezz)
