2082db2d3c in_pcbdetach: move ip_freemoptions() under softnet_lock for now (this will
be changed back once other IP paths become MP-safe).  Same for IPv6 routine.

This partially reverts 1.150 of in_pcb.c and 1.127 of in6_pcb.c changes.

d575eb5454 * split PRU_PEERADDR and PRU_SOCKADDR function out of pr_generic()
usrreq switches and put into separate functions
  xxx_{peer,sock}addr(struct socket *, struct mbuf *).

    - KASSERT(solocked(so)) always in new functions even if request
      is not implemented

    - KASSERT(pcb != NULL) and KASSERT(nam) if the request is
      implemented and not for tcp.

* for tcp roll #ifdef KPROF and #ifdef DEBUG code from tcp_usrreq() into
  easier to cut & paste functions tcp_debug_capture() and
tcp_debug_trace()

    - functions provided by rmind
    - remaining use of PRU_{PEER,SOCK}ADDR #define to be removed in a
      future commit.

* rename netbt functions to permit consistency of pru function names
  (as has been done with other requests already split out).

    - l2cap_{peer,sock}addr()  -> l2cap_{peer,sock}_addr_pcb()
    - rfcomm_{peer,sock}addr() -> rfcomm_{peer,sock}_addr_pcb()
    - sco_{peer,sock}addr()    -> sco_{peer,sock}_addr_pcb()

* split/refactor do_sys_getsockname(lwp, fd, which, nam) into
  two functions do_sys_get{peer,sock}name(fd, nam).

    - move PRU_PEERADDR handling into do_sys_getpeername() from
      do_sys_getsockname()
    - have svr4_stream directly call do_sys_get{sock,peer}name()
      respectively instead of providing `which' & fix a DPRINTF string
      that incorrectly wrote "getpeername" when it meant "getsockname"
    - fix sys_getpeername() and sys_getsockname() to call
      do_sys_get{sock,peer}name() without `which' and `lwp' & adjust
      comments
    - bump kernel version for removal of lwp & which parameters from
      do_sys_getsockname()

note: future cleanup to remove struct mbuf * abuse in
xxx_{peer,sock}name()
still to come, not done in this commit since it is easier to do post
split.

909a1fc699 backout change that made pr_stat return EOPNOTSUPP for protocols that
were not filling in struct stat.

decision made after further discussion with rmind and investigation of
how other operating systems behave.  soo_stat() is doing just enough to
be able to call what gets returned valid and thus justifys a return of
success.

additional review will be done to determine of the pr_stat functions
that were already returning EOPNOTSUPP can be considered successful with
what soo_stat() is doing.
