net/socket: factor out helpers for memory and queue manipulation
Basic sock operations that udp code can use with its own
memory accounting schema. No functional change is introduced
in the existing APIs.
v4 -> v5:
- avoid whitespace changes
v2 -> v4:
- avoid exporting __sock_enqueue_skb
v1 -> v2:
- avoid export sock_rmem_free
