net: Make userland include of netlink.h more sane.
Currently userland will barf when including linux/netlink.h unless it
precisely includes sys/socket.h first. The issue is where the
definition of "sa_family_t" comes from.
We've been back and forth on how to fix this issue in the past, see:
http://thread.gmane.org/gmane.linux.debian.devel.bugs.general/622621
http://thread.gmane.org/gmane.linux.network/143380
Ben Hutchings suggested we take a hint from how we handle the
sockaddr_storage type. First we define a "__kernel_sa_family_t"
to linux/socket.h that is always defined.
Then if __KERNEL__ is defined, we also define "sa_family_t" as
equal to "__kernel_sa_family_t".
Then in places like linux/netlink.h we use __kernel_sa_family_t
in user visible datastructures.
