Check if the name passed to DNS_Name2IPAddress() is an IP address
before calling getaddrinfo(), which can be much slower and work
differently on different systems.
Ignore IPv6 addresses returned by getaddrinfo() that have a non-zero
scope ID to avoid silently ignoring the ID if it was specified with the
% sign in the provided string.
This can be removed when the scope ID is returned from the function and
the callers handle it.
Specify SOCK_DGRAM socktype instead of SOCK_STREAM in hints for
getaddrinfo() as chronyd is (and will mainly be) using the returned
addresses to open UDP sockets. This shouldn't make a difference in
practice, but it might avoid some confusion.
This is apparently needed on system which keep nameservers specified
in /etc/resolv.conf even when there is no network connection. Should be
used with care as invalid names will be retried forever.
Instead of retrying to resolve it in the function and blocking for a
long time, return a TryAgain status and let the caller retry it later if
necessary.
I switch to the git version of chrony. Accidently this version did not
talk to by lokal server at 192.168.192.4. Instead it continuosly tried
255.255.192.4 :-( .
Tracked that down to "char", "unsigned char" issue in nameserv.c:

It doesn't actually fix anything, it just shuts up -Wall, so it's certainly an
optional type of patch.
This is a verbatim copy of the files at that stage of the repository that was
built from the CVS import. It allows future development to see a bit of recent
history, but without carrying around the baggage going back to 1997. If that
is really required, git grafts can be used.
