[PATCH net-next 00/10] net/tcp: TCP-AO and TCP-MD5 tracepoints

I tried to split it a bit, maybe I could even go further and split by
TRACE_EVENT_CLASS() changes, but not sure if it adds any value.
But at least all preparation patches are separate.

I wasn't sure if I should just remove tcp_hash_fail() as I did in this
version, or rather put it under CONFIG_TCP_..., making it disabled by
default and with a warning of deprecated, scheduled for removal.
Maybe this won't cause any problems for anybody and I'm just too
cautious of breaking others.

Anyways, version 1, thanks for any reviews!
