There are two obvious ways to go for an embedded client.

One way would be to use the sntp code as the base.

The other would be to either use the current NTP codebase and use the
configure options to disable all the refclocks and anything else you
didn't want, or wait until we're done with the post-4.2.8 rewrite.  For
post-4.2.8, we're looking at having a "client core" with any refclock
code being handled a separate process.
