2.0+, 1.8, commit ca1a846290, but affects older and newer commits as well

The problem still occurs with V2.0 (tcltls-20260122101940-ba2ee7744c).

The delivered patch has not bee integrated into the source. Here is an updated version of the patch (starting  around tlsIO.c:230).

```
	if (ret <= 0) {
	    /*
	     * Problem here when socket is not async and still not
	     * connected, avoid to loop endlessly. This happens to be the case
	     * the the destination IP is reachable but no service responds on
	     * the requested port. Tcl http does not put the socket in async
	     * mode until connected so we need to allow the Tcl event loop to
	     * catch the timeout and sit on a vwait for the http token.
	     * Test case which yields hang in endless loop here without this patch is:
	     * package require http;
	     * package require tls;
	     * ::http::register https 443 [list ::tls::socket -autoservername true]
	     * set tok [http::geturl https://localhost:8143/info -timeout 3000]
	     * http::status $tok;
	     */
	    if(statePtr->flags & TLS_TCL_ASYNC) {
		if (rc == SSL_ERROR_WANT_CONNECT || rc == SSL_ERROR_WANT_ACCEPT) {
		    bioShouldRetry = 1;
		} else if (rc == SSL_ERROR_WANT_READ) {
		    bioShouldRetry = 1;
		    statePtr->want |= TCL_READABLE;
		} else if (rc == SSL_ERROR_WANT_WRITE) {
		    bioShouldRetry = 1;
		    statePtr->want |= TCL_WRITABLE;
		}
	    }
	}
```

This fixes the described problem. Please integrate the patch in to 2.0+.
