ab2adc20f2 Have kevent() automatically restart if interrupted by a signal. If this 
is not desired, then the user can register an EV_SIGNAL filter to
explicitly catch a signal event.

Change requested by: jayanth, ps, peter
		     "Why is kevent non-restartable after a signal?"

2ba03123c5 Fix a bug which would cause some knotes to get lost when two kqueues 
were being used in a process at the same time.

d2693dbbc4 Add code so that the udata field is preserved across a TRACK event. 
When re-adding an event, do not reset the event state.  If the event was
pending, it will remain pending.  This allows the user to change the udata
field after the event was registered, while not losing any events which
have already occurred.

d36cb22369 malloc(..., M_WAITOK) will not return NULL, so remove the error 
handling for this case (which was slightly broken anyway)

Fix up some whitespace problems while I'm here too.

e39756439c Back out the previous change to the queue(3) interface. 
It was not discussed and should probably not happen.

740a1973a6 Change the way that the queue(3) structures are declared; don't assume that 
the type argument to *_HEAD and *_ENTRY is a struct.

b4b03426ca Fix one bug where the kn_head list could be manipulated without 
spl() protection in the case of a copyout error.

Add missing spl calls around the intial activation call that is
done when when the kevent is added.

Add two KASSERT macros to help catch errors in the future.
