We're using a buffered I/O, so you could create a public
fill_buffer_for_at_least(pb, size) which does the obvious. After a
succesful call to this function, we would guarantee that the next size
bytes would be available without blocking.

One call to this function at the top of get_packet() where size =
HEADER_SIZE, and one in parse_packet() where size =
next_packet_data_size.
