wavpack: read first byte from wvc stream
Instead of manually waiting for the input stream to become ready (to catch server errors), just read the first byte. Since the wavpack_input has the capability to push back one byte, we can simply re-feed it. Advantage is: decoder_read() handles everything for us, i.e. waiting for the stream, polling for decoder commands and error handling.
