Added syscall to update filestats (size) from pager.

Forks and COW situations show that we need vm objects rather than vm_files.
...
This is the first commit towards implementing vm object based paging with
right COW methods.

Preparing to add utcbs at disjoint virtual addresses.
...
This will help when syscalls have long arguments individual
utcbs can be mapped to server tasks and kept mapped in until the
tasks die, as opposed to map requests every time a server task maps
a different utcb at the same virtual address.
The changes have preparation code to also passing the utcb info
through the stack as part of the environment.
To sum up env and arg regions have also been added above the stack and
env region is to be used to pass on the utcb address information at
task startup.

Fixed various minor issues.
...
Tag setting before ipc via l4 libraries don't seem to work, whereas
c0 internally generated ipcs do it correctly.
