[PATCH] Include netinet/in.h in include/experimental/internet

[Andreas Tobler]

Hi all,

I'm going to commit the attached patch to trunk.
It is preapproved by Jonathan. (via #irc)

On FreeBSD the netinet/in.h header is not included by arpa/inet.h, so do 
the include if we have the _GLIBCXX_HAVE_NETINET_IN_H defined.

This makes all the experimental/net/internet test cases pass here.

Any comments?

TIA,
Andreas
