Misc fixes and changes #3
Conversation
This helps recovering from communication errors when connecting to already "busy" line mid-message.
This is causing some issues when using cross-compilation.

I think by removing this you actually made self.buffer totally useless: it is never written, only read, but it will always be empty. The whole idea of this buffer was to support partial messages. On my experience it was possible to receive partial messages in read_and_decode, that's why we had to save it in a buffer and append the next message to it and do the decoding on the merged message (not just the currently received stuff).
Of course it might be possible that your device is never sending these partial messages, and you have no need for this. But are you sure you have to remove this functionality? Is it causing a problem for you, or you just wanted to simplify things?

Ok, this buffer thing was something we really struggled with whenever we connected our Coin Acceptor to the cctalk bus and received the data mid-packet.
Right now we have 30+ coin-acceptor devices working 24/7 and we haven't seen any issues on cctalk side.
@kmuuk Ideas?

If needed, I can split it into separate pull requests.
