Upto now AX.25 was using two separate structures for it's sockets.  One=
,
ax25_cb described the entire actual AX.25 connection.  The other was
the standard struct sock.

This patch combines both into struct ax25_sock which is more in line wi=
th
current practice.  An AX.25 speciality was that a ax25_cb could exist
without a struct sock referencing it.  Keep that alive for now by keepi=
ng
the old struct sock *sk member of ax25_cb in struct ax25_sock.  This no=
w
just has become a struct-internal pointer.

Aside of wanrouter AX.25 has also been the last member of struct
sock.sk_protinfo.  With net/wanrouter being considered hopeless code an=
d
an application-level solution being prefered these days this means we n=
ow
can delete sk_protinfo.
