Treat the packet length as unsigned - it shouldn't be negative in the file. If it is, that'll probably cause the sscanf to fail, so we'll report the file as bad. Check it against WTAP_MAX_PACKET_SIZE to make sure we don't try to allocate a huge amount of memory, just as we do in other file readers. Use the now-validated packet size as the length in ws_buffer_assure_space(), so we are certain to have enough space, and don't allocate too much space. Merge the header and packet data parsing routines while we're at it.
