Ollivier Robert a3275ecc3f Re-apply patch from bin/92839 to avoid two possible buffer overflows. For an
unknown reason, this seems to have never been applied to vendor sources.

NTP 4.2.4p5
originals can be found on http://www.ntp.org/downloads.html
Import
------
For the import of NTP the following files were removed:
ports/* NT files
html/pic/* GIF files
ElectricFence/* Support for the ElectricFence library
(only useful if you want to debug ntpd)
html/build/hints/solaris.xtra.4095849 Trigger merge conflict script
The stripped down version was created using FREEBSD-Xlist during extraction:
tar -X FREEBSD-Xlist -xvzf ntp-4.2.4p5.tar.gz
mv ntp-4.2.4p5 4.2.4p5

Updating usr.sbin/ntp
---------------------
./configure --disable-all-clocks --enable-NMEA --enable-ONCORE
--enable-RAWDCF --with-crypto --disable-debugging
--enable-LOCAL-CLOCK --with-sntp --with-arlib --prefix=/usr
config.h was generated by running configure and excluding almost all clock
drivers (what is included is DCF77 -- what I use --, NMEA, Motorola OnCORE
and local clocks).
The file is then edited to edit the value of "NO_PARENB_IGNPAR" because we
need to set no parity on the serial port (needed for DCF77). All clock
drivers are then disabled (some of them are included by default by ntpd).
Note that there are two #ifdef to support other architectures (WRT to long
size and endianness). They'll need to be redone for each upgrade to the
vendor branch to keep config.h in sync.
ntpd/ntp_control.c is now the only file that is different from the vendor
branch for unsigned char/int fixes and removal of a DoS.
Documentation in /usr/share/doc/ntp is generated from the HTML files with
lynx (without the GIF files of course).
One patch needs to be applied after that to close two buffer overflows. See
bin/92839 for details.
