[NETNS]: Introduce a netns_core structure. There's already some stuff on the struct net, that should better be folded into netns_core structure. I'm making the per-proto inuse counter be per-net also, which is also a candidate for this, so introduce this structure and populate it a bit.

[SOCK][NETNS]: Add the percpu prot_inuse counter in the struct net. Such an accounting would cost us two more dereferences to get the percpu variable from the struct net, so I make sock_prot_inuse_get and _add calls work differently depending on CONFIG_NET_NS - without it old optimized routines are used. The per-cpu counter for init_net is prepared in core_initcall, so that even af_inet, that starts as fs_initcall, will already have the init_net prepared.
