feda1a4372 Restore netstat -M functionality for most statistics on core dumps. In
general, when support was added to netstat for fetching data using sysctl,
no provision was left for fetching equivalent data from a core dump, and
in fact, netstat would _always_ fetch data from the live kernel using
sysctl even when -M was specified resulting in the user believing they
were getting data from coredumps when they actually weren't.  Some specific
changes:
- Add a global 'live' variable that is true if netstat is running against
  the live kernel and false if -M has been specified.
- Stop abusing the sysctl flag in the protocol tables to hold the protocol
  number.  Instead, the protocol is now its own field in the tables, and
  it is passed as a separate parameter to the PCB and stat routines rather
  than overloading the KVM offset parameter.
- Don't run PCB or stats functions who don't have a namelist offset if we
  are being run against a crash dump (!live).
- For the inet and unix PCB routines, we generate the same buffer from KVM
  that the sysctl usually generates complete with the header and trailer.
- Don't run bpf stats for !live (before it would just silently always run
  live).
- kread() no longer trashes memory when opening the buffer if there is an
  error on open and the passed in buffer is smaller than _POSIX2_LINE_MAX.
- The multicast routing code doesn't fallback to kvm on live kernels if
  the sysctl fails.  Keeping this made the code rather hairy, and netstat
  is already tied to the kernel ABI anyway (even when using sysctl's since
  things like xinpcb contain an inpcb) so any kernels this is run against
  that have the multicast routing stuff should have the sysctls.
- Don't try to dig around in the kernel linker in the netgraph PCB routine
  for core dumps.

Other notes:
- sctp's PCB routine only works on live kernels, it looked rather
  complicated to generate all the same stuff via KVM.  Someone can always
  add it later if desired though.
- Fix the ipsec removal bug where N_xxx for IPSEC stats weren't renumbered.
- Use sysctlbyname() everywhere rather than hardcoded mib values.

7b95a1ebbd Achieve WARNS=2 by using uintmax_t to pass around 64-bit quantities,
including to printf().  Using uintmax_t is also robust to further
extensions in both the C language and the bitwidth of kernel counters.

100b98db75 Add support for printing IPSEC protocol stats if the kernel was compiled
with FAST_IPSEC rather than the KAME IPSEC stack.

Note that the output of "netstat -s -p ipsec" differs depending on which
stack is compiled into the kernel since they each keep different stats.
This delta also adds the "esp", "ah", and "ipcomp" protocol stats, which
are also available when the kernel is compiled with the FAST_IPSEC stack
(e.g. "netstat -s -p esp").

6cc6f12231 Add __FBSDID. Replace local variable sin by sockin to not conflict with sin(3).
Use warnx() instead of warn() when error message is not of any interest. Add
prototypes.

a01e3379df Warns cleanups for netstat:
1) Include arpa/inet.h for ntohs.
2) Constness fixes.
3) Fix shadowing except for "sin" which shouldn't be in scope.
4) Remove register keyword.
5) Add missing initialsers to user defined structs.
5) Make prototype of netname6 globally visable.
6) Use right macros for printing syncache stats (even though entrie isn't
   a word).

3384154590 Sync with recent KAME.
This work was based on kame-20010528-freebsd43-snap.tgz and some
critical problem after the snap was out were fixed.
There are many many changes since last KAME merge.

TODO:
  - The definitions of SADB_* in sys/net/pfkeyv2.h are still different
    from RFC2407/IANA assignment because of binary compatibility
    issue.  It should be fixed under 5-CURRENT.
  - ip6po_m member of struct ip6_pktopts is no longer used.  But, it
    is still there because of binary compatibility issue.  It should
    be removed under 5-CURRENT.
