- Remove ip_route.h for the license clash

- Update to version 2.4.3
Changes
* Add strlcat() replacement from OpenBSD, use instead of strcat()
* smcrouted should never log to system console, proposed by Westermo
Fixes
* smcrouted fails to join multicast groups on interfaces that do not
yet have an IP address when smcrouted starts up, or when it receives
SIGHUP, e.g. DHCP client interfaces. This patch release adds a timer
refresh of interface addresses that retries multicast group joins
until an address is set. This is similar to issue #55, but does not
handle interfaces that do not exist yet.
* Make sure Linux alias interfaces (baseif:num) are registered as
baseif. Westermo found that use of alias interfaces cause multiple
VIFs to be registered for the same base interface causing multicast
routes to use the wrong inbound or outbound VIF. Alias interfaces
use the same underlying physical interface so only one VIF needed.
* Fix display of route counters and column alignment
* Simplify utimensat() replacement, AT_SYMLINK_NOFOLLOW unused

- Update to version 2.4.2
Changes
* Add wrapper script smcroute for use with old style startup scripts
* Add symlinks to man pages for smcrouted.8 and smcroutectl.8
* Update SysV init script, daemon now called smcrouted
Fixes
* Fix #96: A .conf line may be missing final newline, this is fine
* Spellcheck smcroute.conf example
