socket: clear error even when peeking

The error has already been reported and it's pointless requiring another
recv(2) call just to clear it.

socket: report receive buffer overflows

Add soroverflow() which increments the overflow counter, sets so_error
to ENOBUFS and wakes the receive socket up.
Replace all code that manually increments this counter with soroverflow().
Add soroverflow() to raw_input().

This allows userland to detect route(4) overflows so it can re-sync
with the current state.

Nowadays we can create new kernel threads late after boot, so if we are
unable to find physically continous pages for their uarea, just allocate
them via uvm_km_alloc(), that is: make cpu_uarea_alloc() fail instead
of panic. cpu_uarea_free() already deals with this.

Should fix PR port-alpha/53077.

pass valsize for getsockopt like we do for setsockopt
make sure that we have enough space, don't require the exact size
(Tom Ivar Helbekkmo)

1) "#define ipi_spec_dst ipi_addr" in <netinet/in.h>
2) Change the IP_RECVPKTINFO option to control the generation of
  IP_PKTINFO control messages, the way it's done in Solaris.
3) Remove the superfluous IP_RECVPKTINFO control message.
4) Change the IP_PKTINFO option to do different things depending on
  the parameter it's supplied with:
  - If it's sizeof(int), assume it's being used as in Linux:
    - If it's non-zero, turn on the IP_RECVPKTINFO option.
    - If it's zero, turn off the IP_RECVPKTINFO option.
  - If it's sizeof(struct in_pktinfo), assume it's being used as in
    Solaris, to set a default for the source interface and/or
    source address for outgoing packets on the socket.
5) Return what Linux or Solaris compatible code expects, depending
  on data size, and just added a fallback to a Linux (and current NetBSD)
  compatible value if the size is unknown (as it is now), or,
  in the future, if the calling application specifies a receiving
  buffer that doesn't match either data item.

Fix the handling of the state returned from pfil_run_hooks().

pfil_run_hooks() invokes any registered packet filters on the packet
being handled.  It may return a (non-zero) errno, indicating that a
filter has decided that the packet should be discarded, and has freed
the mbuf.  While a non-error (0) return usually means that the packet
should be processed normally, a filter may still free the mbuf if the
packet is a fragment, and the filter is holding it for reassembly and
future evaluation.  Therefore, there must be separate tests for the
return value and for a possible discarded packet.  (See pfil(9).)

OK: christos, martin
