block first read and force synchrnous handshaking in TLS connection

Couldn't find any other way to solve this easily. So here's the first try.

>From the source code comment:

  /**
   * If we have a TLS connection, we are doing implicit auto-handshaking
   * (which happens in a separate thread) when we first call the read
   * functions in fill_raw_bytes. If we use non-blocking read here, we
   * would get a G_IO_ERROR_TIMED_OUT during handshaking and we would
   * just exit the dispatch read. So, we want the implicit
   * auto-handshaking to happen synchronously.
