This is a stream of data arriving in chunks. With a native TCP stack,
it will serve individual buffers as arriving from the network interface and
queued by the TCP stack. With the hosted stack (bsd_data_source_impl),
we unfortunately have to allocate each chunk individually.

Add a share() method that enables reference counting for the packet and
returns a clone. The packet's deleter will only be invoked after all clones
are destroyed.
This is useful for tcp, which keeps a packet in the unacknowledged transmit
queue while sending it lower down the stack.
