Modified Files:
        syssrc/sys/kern: kern_ktrace.c

Log Message:
- Allocate the ktrace operation header on the stack rather than using
  MALLOC()/FREE().
- In ktrgenio():
        - Don't allocate the entire size of the I/O for the temporary
          buffer used to write the data to the trace file.  Instead,
          do it in page-sized chunks.
        - As in uiomove(), preempt the process if we are hogging the CPU.
        - If writing to the trace file errors, abort rather than continuing
          to loop through the buffer.
