Use UPAGES_HOLE instead of UPAGES in case it's changed some time.

Browse Source 
Rename the PT* index KSTK* #defines to UMAX*, since we don't have a kernel
stack there any more..

These are used to calculate VM_MAXUSER_ADDRESS and USRSTACK, and really
do not want to be changed with UPAGES since BSD/OS 2.x binary compatability
depends on it.
