  Modified files:
    sys/conf             options 
    sys/sys              ktr.h 
    sys/kern             kern_ktr.c 
  Log:
  - Remove much of the inlining of the KTR tracepoints into a ktr_tracepoint()
    function declared in kern_ktr.c.  The only inline checks left are the
    checks that compare KTR_COMPILE with the supplied mask and thus should
    be optimized away into either nothing or a direct call to ktr_tracepoint().
  - Move several KTR-related options to opt_ktr.h now that they are only
    needed by kern_ktr.c and not by ktr.h.
  - Add in the ktr_verbose functionality if KTR_EXTEND is turned on.  If the
    global variable 'ktr_verbose' is non-zero, then KTR messages will be
    dumped to the console.  This variable can be set by either kernel code
    or via the 'debug.ktr_verbose' sysctl.  It defaults to off unless the
    KTR_VERBOSE kernel option is specified in which case it defaults to on.
    This can be useful when the machine locks up spinning in a loop with
    interrupts disabled as you might be able to see what it is doing when it
    locks up.
