ntpd: add support for MD5/SHA1 message authentication

Add support for MD5 message authentication as described in RFC 5905.
This patch also supports SHA1 authentication.
The key file format is the same file format as used by ntpd.
The configuration file format follows standard Unix conventions
(# comments) with lines consist of the following fields separated by whitespace:
<key identifier, [1,65535]> <SHA1|MD5> <an ASCII string of up to 20 characters|an octet string [a-zA-F0-9] of up to 40 characters>.

will include all files in the named directory. Similar to the Busybox
version of the "source" stanza, this version of source-directory does
not currently support shell wildcards.
We only check that the stanza starts with "source-dir" as ifupdown does[2].

ntpd: show real, unclamped delays on low-latency networks
...
On fast network, I've seen "delay:0.002000" shown for all packets,
thus completely losing information on what real delays are.
The new code is careful to not reject packets with tiny delays
if the delay "grows a lot" but is still tiny:
0.000009 is "much larger" than 0.000001 (nine times larger),
but is still very good small delay.
