If present in the route message, otherwise simply skip it.

So you can compile rtnl-route-event via `make check'

Now, both IPv4 and IPv6 are supported simultaneously in one single file.
While at it:
* I moved the declarations to the beginning of the main function.
* Renamed mask by prefix, which seems more appropriate to me.
* Use RTPROTO_STATIC, as the route has been added by the administrator.
* Set NLM_F_ACK, so we get a report from the kernel about our query and
treat reply from the kernel.
* Stricter argc checking.
* Use perror instead of printf for error reporting.

[ Pablo has modified the original patch modified to fix some compilation
warnings with gcc-4.7 and select the protocol family as argument from
the command line. ]

I have decided to release the examples in this library in the public
domain. Jan Engelhardt, who has been the sole contributor so far, has
agreed with this re-licensing by communication via e-mail.

This patch reworks mnl_nlmsg_fprintf. It breaks backward compatibility
of this function, there was no way to improve it without doing so
(and we are still in time to break thing, BTW).

Davem spotted during the Netfilter Workshop that user-space applications
should use 8KB buffers for recv(). I accidentally found that NFLOG is
not following this approach (in this case we're using 131072 bytes
messages), we have to document this.
Anyway, according to linux/netlink.h (and to complete this log message):
"skb should fit one page. This choice is good for headerless malloc.
But we should limit to 8K so that userspace does not have to
use enormous buffer sizes on recvmsg() calls just to avoid
MSG_TRUNC when PAGE_SIZE is very large."

Besides that -ldl should be in _LDADD (not _LDFLAGS), I do not see any
dlopen calls at all that would make the library a requirement.
I also see no reason to use -Wc,-nostartfiles.
