More cleanup of the sockets c/r code. Now that we use the methods from
struct proto_ops (checkpoint,restore), we no longer need the prefix
"sock_unix_..." for function names in net/unix/checkpoint.c; Instead
we follow the convention (e.g. in net/unix/afunix.c) "unix_...".
Speaking about code conventions, it is also customary to use 'sock'
for a struct socket, and a 'sk' for struct sock. This patch also makes
changes accordingly where necessary.
