[bpf-next 2/2] bpf: add BPF_SOCK_OPS_STATS_CB for tcp_stats()

Introuce this new op BPF_SOCK_OPS_STATS_CB for tcp_stats() such that it can be traced via BPF on a per socket basis. There's one argument in BPF_SOCK_OPS_STATS_CB, which is Linux MIB index LINUX_MIB_* to indicate the TCP event. All these Linux MIBs are defined in include/uapi/linux/snmp.h.
