TFTP: Improve dissection of ERROR packets.
Instead of annotating every TFTP ERROR packet as "TFTP blocksize out of range",
let's flag them as TFTP error packets using their own expert info type.
Let's also try to figure out whether an ERROR packet represents a "close"
operation after a transfer-size ("tsize") query. Such ERROR packets aren't
really errors, so we can use a separate expert info type to report those with
lower severity.
Testing Done: On macOS 10.12.6, built Wireshark, and examined a handful of
TFTP packet captures in the GUI, including tsize probes and real errors
(file not found, permission denied). From the menu, chose Analyze > Expert
Information, and saw the tsize probes listed together at "Chat" severity,
and actual errors reported at "Warning" severity, all appropriately labeled.
