This patch introduces a retransmit functionality for a lowcomms message handle. It's just allocates a new buffer and transmit it again, no special handling about prioritize it because keeping bytestream in order. To avoid another connection look some refactor was done to make a new buffer allocation with a preexisting connection pointer.
