Kevin O'Connor 9a44a20a9d command: Check for reentrant calls to sendf()
Allow sendf() to be called from irq and timer context - check for the
case where sendf() is called while already in sendf() and simply
discard those messages.  This makes it safe to use output() debugging
calls even in irq and timer context.
