	Per the resolution of POSIX bug 0000779 (note 0002050) add support for using 'i'
	as a case insensitive flag.

	Add regression test for recently added 'i' flag in r259132.

	the i modifier was added in r259132 since POSIX recently agreed to add
	it. Switch uses of /I to /i.

  Apply patch from upstream Heimdal for encoding fix

  RFC 4402 specifies the implementation of the gss_pseudo_random()
  function for the krb5 mechanism (and the C bindings therein).
  The implementation uses a PRF+ function that concatenates the output
  of individual krb5 pseudo-random operations produced with a counter
  and seed.  The original implementation of this function in Heimdal
  incorrectly encoded the counter as a little-endian integer, but the
  RFC specifies the counter encoding as big-endian.  The implementation
  initializes the counter to zero, so the first block of output (16 octets,
  for the modern AES enctypes 17 and 18) is unchanged.  (RFC 4402 specifies
  that the counter should begin at 1, but both existing implementations
  begin with zero and it looks like the standard will be re-issued, with
  test vectors, to begin at zero.)

  This is upstream's commit f85652af868e64811f2b32b815d4198e7f9017f6,
  from 13 October, 2013:
  % Fix krb5's gss_pseudo_random() (n is big-endian)
  %
  % The first enctype RFC3961 prf output length's bytes are correct because
  % the little- and big-endian representations of unsigned zero are the
  % same.  The second block of output was wrong because the counter was not
  % being encoded as big-endian.
  %
  % This change could break applications.  But those applications would not
  % have been interoperating with other implementations anyways (in
  % particular: MIT's).

Bump __FreeBSD_version accordingly and add a note in UPDATING.

MFC r258819,258928:

Add new sysctl, kern.supported_archs, containing the list of FreeBSD
MACHINE_ARCH values whose binaries this kernel can run. This patch provides
a feature requested for implementing pkgng ABI identifiers in a robust
way.

The list is designed to indicate whether, say, an i386 package can be run on
the current system. If kern.supported_abis contains "i386", then the answer
is yes. Otherwise, the answer is no.

At the moment, this only supports MACHINE_ARCH and MACHINE_ARCH32. As we
gain support for more interesting combinations, this needs to become more
flexible, possibily through the sysent framework, along with the
hw.machine_arch emulation immediately preceding this code in kern_mib.c.

        Fix several problems that can cause panics on kldload and kldunload.

        * kproc_create(fasttrap_pid_cleanup_cb, ...) gets called before
          fasttrap_provs.fth_table gets allocated.  This can lead to a panic
          on module load, because fasttrap_pid_cleanup_cb references
          fasttrap_provs.fth_table.  Move kproc_create down after the point
          that fasttrap_provs.fth_table gets allocated, and modify the error
          handling accordingly.

        * dtrace_fasttrap_{fork,exec,exit} weren't getting NULLed until
          after fasttrap_provs.fth_table got freed.  That caused panics on
          module unload because fasttrap_exec_exit calls
          fasttrap_provider_retire, which references
          fasttrap_provs.fth_table.  NULL those function pointers earlier.

        * There wasn't any code to destroy the
          fasttrap_{tpoints,provs,procs}.fth_table mutexes on module unload,
          leading to a resource leak when WITNESS is enabled.  Destroy those
          mutexes during fasttrap_unload().
