sys/stack.h:1.4 from HEAD to RELENG_7:

  Break out stack(9) from ddb(4):

  - Introduce per-architecture stack_machdep.c to hold stack_save(9).
  - Introduce per-architecture machine/stack.h to capture any common
    definitions required between db_trace.c and stack_machdep.c.
  - Add new kernel option "options STACK"; we will build in stack(9) if it
    is defined, or also if "options DDB" is defined to provide
    compatibility with existing users of stack(9).

  Add new stack_save_td(9) function, which allows the capture of a
  stacktrace of another thread rather than the current thread, which the
  existing stack_save(9) was limited to.  It requires that the thread be
  neither swapped out nor running, which is the responsibility of the
  consumer to enforce.

  Update stack(9) man page.

  Build tested:   amd64, arm, i386, ia64, powerpc, sparc64, sun4v
  Runtime tested: amd64 (rwatson), arm (cognet), i386 (rwatson)

Merge i386/stack_machdep.c:1.2 from HEAD to RELENG_7:

  Remove duplicate $FreeBSD$ tag.

Merge files.pc98:1.359, pc98/include/stack.h:1.1 from HEAD to RELENG_7:

  Catch up pc98 for i386 stack(9) changes:

    Add stub stack.h for pc98 that includes i386 pc98.

    Add i386 stack_machdep.c to files.pc98.
