This speeds up syncing - now happens only just
two replies from a peer. Especially useful for "ntpd -q".
Shouldn't have ill effects: if we chose a bad peer,
we will discover it later and switch to another one.
The code is even smaller this way.

We wanted to detect when tv_sec = unsigned1 - unsigned2
underflows by looking at tv_sec's sign. But if tv_sec
is long and it is wider than unsigned, we get unsigned -> long
conversion which is in this case never negative.

This fixes a regression introduced with commit 78854520 (modprobe:
revert checking for /, stop doing basename() on modprobe args,
2015-01-01) that broke modprobe options stored in /etc/modprobe.conf and
/etc/modprobe.d/*.conf.
This also fixes modprobe -r

If the :r command is used to read a file after the last line of the
buffer the last line of the buffer and the first line of the file
are joined. An extra blank line appears at the end of the buffer.

The insertion point is normally at the start of the line following the
specified line. When the specified line is the last one the next_line
function baulks at moving to the non-existent following line.

Commit 32afd3a introduced these regressions on the master branch:
Starting vi with no filename on the command line gives the status message
"'(null)' Bad address" instead of "- No file 1/1 100%".
Starting vi with a non-existent file on the command line gives the status
message "'new.txt' No such file or directory" instead of "- new.txt 1/1 100%"

OpenNTPd is licensed under ISC-style license so it's good idea to keep
ntpd applet under same license to avoid mess, instead of having
our changes to be under GPL.

Based on the following user report:
I ran into an issue where I was seeing a long delay in the scripts called
in udhcp_run_script. I was using an old version of OpenWrt (kamikaze)
and a satellite modem. An NTP script was being called and the modem
would sometimes take a long time to respond to the DNS lookup when
it was offline.
This delay started affecting my lease time. The lease that I would
get from my satellite modem before it was online would be short:
only 60 seconds. The delay with NTP and the modem would typically
be about 18 seconds. This would cause the first DHCP renew request
from dhcpc to be a little late. Under certain circumstances,
I could even see the first DHCP renew to occur after the lease
had expired!
