Removed dependency on hard-coded pager id. Pager id is now passed
as an environment string `pagerid' to tasks. Alternatively, this
could take space in the utcb of each task.
- Need to remove old versions
- Need to merge the two.
- Need to investigate occasional page fault on NMOP sequence. (resembles an error ipc_extended test)
Could be related to new page cache read/write routines.
test0 now successfully runs its beginning.
test0 SConscript has a dependency problem.
Issues to be investigated:
- vm_file and vnodes need to be merged fully in all functions.
- libposix shared page references need to be removed.
- Any references to VFS_TID, PAGER_TID need to be removed.
