  Log:
  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)
