NTP: fix detection of larger MAC sizes, remove Autokey support
Autokey was not properly supported, the v2 version check looked at the
wrong field (Code instead of Field Type). Since nobody noticed it, let's
remove it to simplify the code.
Improve the Extension Field (EF) heuristics to ensure that larger digest
sizes such as SHA-512 are recognized, and to support messages without
MAC. Previously only MD5 and SHA-1 were supported as these are the only
ones that are defined by the RFCs.
The ntp_ext_field_types array was generated by:
curl -s
https://www.iana.org/assignments/ntp-parameters/ntp-parameters-3.csv |
awk -F, 'NR>=2{printf "{ %s, \"%s\" },\n", $1, $2}' | sort -n
Tested with md5_dgrams.pcapng and sha1_dgrams.pcapng (Bug 11580) and
NTP-with-mac.pcap (Bug 16640). Also checked against the NTS capture
(go_embeded.pcapng, bug 16222), but TCP reassembly is not supported so
the last part of the first segment is wrongly dissected as MAC.
Bug: 16640
