  Log:
  Update in_pcb-derived basic socket types following changes to
  pru_abort(), pru_detach(), and in_pcbdetach():
  
  - Universally support and enforce the invariant that so_pcb is
    never NULL, converting dozens of unnecessary NULL checks into
    assertions, and eliminating dozens of unnecessary error handling
    cases in protocol code.
  
  - In some cases, eliminate unnecessary pcbinfo locking, as it is no
    longer required to ensure so_pcb != NULL.  For example, in protocol
    shutdown methods, and in raw IP send.
  
  - Abort and detach protocol switch methods no longer return failures,
    nor attempt to free sockets, as the socket layer does this.
  
  - Invoke in_pcbfree() after in_pcbdetach() in order to free the
    detached in_pcb structure for a socket.
