Log Message:
yet another major rework of the generic getpages.
we now do the block allocations for allocating getpages operations
after reading the pages.  for nested i/os, use b_resid rather than
b_bcount to track the amount left to go.   return values for
getpages/putpages are now unix errnos rather than VM_PAGER_*.
readahead is gone again for the moment.
