Removed memory access permissions from configuration for simplicity
...
Access permission bits are required eventually but currently are
not a critical concern and yet they complicate configuration. For
sake of simplicity they are removed to be added later on when
absolutely needed.

Added support for faulty pagers and their threads to become zombies
...
Added support for pagers that fault to suspend and become zombies
along with all the threads that they manage. Zombie killing is to
be done at a later time, from this special zombie queue.
The implementation works same as a suspension, with the added action
that the thread is moved to a queue in kernel container.

Managed to self-destruct pager.
...
Issues:
- A page-faulting thread suspends if receives -1 from pager page fault ipc.
This is fine if pager is about to delete the thread, but it is not if
it is a buggy pager.
- Need to find a way to completely get rid of suspended pager.
- A method of deleting suspended tasks could remedy both cases above.

as an environment string `pagerid' to tasks. Alternatively, this
could take space in the utcb of each task.

Fixed utcb updating issue that was a significant burden.
...
Any thread that touches a utcb inside the kernel now properly checks
whether the utcb is mapped on its owner, and whether the mapped physical
address matches that of the current thread's tables. If not the tables
are updated.
This way, even though page tables become incoherent on utcb address
change situations (such as fork() exit(), execve()) they get updated
as they are referenced.
Since mappings are added only conditionally, caches are flushed only
when an update is necessary.
