Date:           Sun Jan 31 04:40:01 UTC 2016

Modified Files:
        src/sys/kern: kern_event.c
        src/sys/sys: event.h

Log Message:
PR/50730: Benny Siegert: Go kqueue test panics kernel.
- use a marker knote from the stack instead of allocating and freeing on
  each scan.
- add more KASSERTS
- introduce a KN_BUSY bit that indicates that the knote is currently being
  scanned, so that knote_detach does not end up deleting it when the file
  descriptor gets closed and we don't end up using/trashing free memory from
  the scan.
