MFC r263289: Update NetBSD Foundation copyrights to 2-clause BSD

  The NetBSD Foundation states "Third parties are encouraged to change the
  license on any files which have a 4-clause license contributed to the
  NetBSD Foundation to a 2-clause license."

  This change removes clauses 3 and 4 from copyright / license blocks that
  list The NetBSD Foundation as the only copyright holder.

MFC r257650:

Defer loading of kernel and modules if the beastie menu is enabled. Add a
kernel selection menu to the beastie menu. List of kernels is taken from
`kernels' in loader.conf(5) as a space (or comma) separated list of names
to display (up to 9). If not set, default value is "kernel kernel.old".
Does not validate that kernels exist because the next enhancement will be
to allow selection of the root device.

MFC r257821:

Extend loader_delay as-documented in beastie.4th(8) and delay.4th(8),
making it available to architectures that do not use or load the beastie
menu. This is reported to save headaches on some PPC systems where unload
followed by load does not produce the desired results wherein if-given
the opportunity to abort the initial loading sequence, you can customize
the first load.

MFC r243322 (by marcel):

Unbreak amd64 cross-build where amd64 is the target. While clang
may be installed as cc and we don't need to build gcc as a
cross-tools, we still build gcc and thus need cc_tools built
as a build tool. Not doing this results in building gengenrtl with
the target compiler while we need to run it on the build machine.

MFC r262613:

Merge the projects/clang-sparc64 branch back to head.  This brings in
several updates from the llvm and clang trunks to make the sparc64
backend fully functional.

Apart from one patch to sys/sparc64/include/pcpu.h which is still under
discussion, this makes it possible to let clang fully build world and
kernel for sparc64.

Any assistance with testing this on actual sparc64 hardware is greatly
appreciated, as there will unavoidably be bugs left.

Many thanks go to Roman Divacky for his upstream work on getting the
sparc64 backend into shape.

MFC r262985:

Repair a few minor mismerges from r262261 in the clang-sparc64 project
branch.  This is also to minimize differences with upstream.

Pull in r196939 from upstream llvm trunk (by Reid Kleckner):

  Reland "Fix miscompile of MS inline assembly with stack realignment"

  This re-lands commit r196876, which was reverted in r196879.

  The tests have been fixed to pass on platforms with a stack alignment
  larger than 4.

  Update to clang side tests will land shortly.

Pull in r196986 from upstream llvm trunk (by Reid Kleckner):

  Revert the backend fatal error from r196939

  The combination of inline asm, stack realignment, and dynamic allocas
  turns out to be too common to reject out of hand.

  ASan inserts empy inline asm fragments and uses aligned allocas.
  Compiling any trivial function containing a dynamic alloca with ASan is
  enough to trigger the check.

  XFAIL the test cases that would be miscompiled and add one that uses the
  relevant functionality.

Pull in r202930 from upstream llvm trunk (by Hans Wennborg):

  Check for dynamic allocas and inline asm that clobbers sp before building
  selection dag (PR19012)

  In X86SelectionDagInfo::EmitTargetCodeForMemcpy we check with MachineFrameInfo
  to make sure that ESI isn't used as a base pointer register before we choose to
  emit rep movs (which clobbers esi).

  The problem is that MachineFrameInfo wouldn't know about dynamic allocas or
  inline asm that clobbers the stack pointer until SelectionDAGBuilder has
  encountered them.

  This patch fixes the problem by checking for such things when building the
  FunctionLoweringInfo.

  Differential Revision: http://llvm-reviews.chandlerc.com/D2954

Together, these commits fix the problem encountered in the devel/emacs
port on the i386 architecture, where a combination of stack realignment,
alloca() and memcpy() could incidentally clobber the %esi register,
leading to segfaults in the temacs build-time utility.

Pull in r203311 from upstream llvm trunk (by Arnold Schwaighofer):

  ISel: Make VSELECT selection terminate in cases where the condition type has to
  be split and the result type widened.

  When the condition of a vselect has to be split it makes no sense widening the
  vselect and thereby widening the condition. We end up in an endless loop of
  widening (vselect result type) and splitting (condition mask type) doing this.
  Instead, split both the condition and the vselect and widen the result.

  I ran this over the test suite with i686 and mattr=+sse and saw no regressions.

  Fixes PR18036.

With this fix the original problem case from the graphics/rawtherapee
port (posted in http://llvm.org/PR18036 ) now compiles within ~97MB RSS.

MFC r263320:

Add separate patch files for all the customizations we have currently
applied to our copy of llvm/clang.  These can be applied in alphabetical
order to a pristine llvm/clang 3.4 release source tree, to result in the
same version used in FreeBSD.

This is intended to clearly document all the changes until now, which
mostly consist of cherry pickings from the respective upstream trunks,
plus a number of hand-written FreeBSD-specific ones.  Hopefully those
can eventually be cleaned up and sent upstream too.

MFC r262501:

Refresh our implementation of OpenBSD's Blowfish password format.

Notable changes:

 - Support of $2b$ password format to address a problem where very
   long passwords (more than 256 characters, when an integer
   overflow would happen and cause the length to wrap at 256).
 - Updated pseudo code in comments to reflect the reality.
 - Removed our local shortcut of processing magic string and rely
   on the centralized and tigntened validation.
 - Diff reduction from upstream.

For now we are still generating the older $2a$ format of password
but we will migrate to the new format once the format is formally
finalized.

detect this situation, but it was not always checked ahead of invoking
functions that might destroy character devices, like detach, set
configuration, set alternate interface or detach active kernel driver.
