vkernel - Restabilize pmap code, redo kqueue, systimer, and console code
* Remove vm_token and add necessary vm_page spin locks to the vkernel's
pmap code, improving its stability.
* Separate the systimer interrupt and console tty support from the
kqueue subsystem.
Uses SIGURG for systimer
Uses SIGIO for kqueue
Uses SIGALRM for cothread signalling
* The vkernel systimer code now uses a dedicated cothread for timing. The
cothread is a bit of a hack at the moment but is a more direct way of
handling systimers.
* Attempt to fix user%/sys%/intr%/idle% in the systat -vm and
systat -pv output. Still isn't perfect, but it is now more
accurate.
