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.

From Artur Grabowski <art@stacken.kth.se>, with some additional cleanup
by me.
