jch 67927a7a7c Decompose TCP INP_INFO lock to increase short-lived TCP connections scalability:
- The existing TCP INP_INFO lock continues to protect the global inpcb list
  stability during full list traversal (e.g. tcp_pcblist()).

- A new INP_LIST lock protects inpcb list actual modifications (inp allocation
  and free) and inpcb global counters.

It allows to use TCP INP_INFO_RLOCK lock in critical paths (e.g. tcp_input())
and INP_INFO_WLOCK only in occasional operations that walk all connections.
