This is a repost of three tidy-up patches that have been left hanging
without resolution. Please comment.
1. Remove unused D_SUN_LEN declarations from DPIs. (The DPIs connect
to their sockets with accept() which doesn't use D_SUN_LEN.)
2. Use D_SUN_LEN whenever calling connect() on a struct sockaddr_un.
(Some of the calls already did this, this patch makes all of them
do so.)
3. Update a GPL reference in a comment from version 2 to version 3.
