David Greenman a83c285c7e Fixed return status from pagers. Ahem...the previous method would manufacture 
data when it couldn't get it legitimately. :-(

David Greenman 976e77fc9c 1) Some of the counters in the vmmeter struct don't fit well into the Mach VM 
scheme of things, so I've changed them to be more appropriate. page in/ous
   are now associated with the pager that did them. Nuked v_fault as the
   only fault of interest that wouldn't be already counted in v_trap is a VM
   fault, and this is counted seperately.
2) Implemented most of the remaining counters and corrected the counting of
   some that were done wrong. They are all almost correct now...just a few
   minor ones left to fix.

David Greenman 8e58bf6875 Stuff object into v_vmdata rather than pager. Not important which at 
the moment, but will be in the future. Other changes mostly cosmetic,
but are made for future VMIO considerations.

David Greenman fff93ab600 Patches from John Dyson to improve swap code efficiency. 
Religiously add back pmap_clear_modify() in vnode_pager_input until we figure
out why system performance isn't what we expect.

problems that fixing them caused.

David Greenman 16f62314cd Incorporated post 1.1.5 work from John Dyson. This includes performance 
improvements via the new routines pmap_qenter/pmap_qremove and pmap_kenter/
pmap_kremove. These routine allow fast mapping of pages for those
architectures that have "normal" MMUs. Also included is a fix to the
pageout daemon to properly check a queue end condition.
