Due to the LPCR values, nap can already be exited by an
interrupt or decrementer event. Remove EE in the MSR so
that we are guarenteed that we fully enter nap even if
there is a interrupt or decrementer pending.

* Allow page allocation system call to force coalesce if a
contiguous block is unavailable. [long-term enhancement]
* Workaround lack of large contiguous memory for PageTable
test-cases, which require 256K, by allocating a VMM block.
This should be removed when story 43401 is implemented.
[short-term workaround]

* Debug tool for PageManager.
* Support PageMgr allocations of non-2^k size.
* Switch page-allocation to always be in kernel-mode.
While investigating issue 44511, I noticed two problesm with the
memory page allocator (PageManager). First, the allocator did
not support allocations of pages which were not a power of 2,
which would result in pages appearing to "leak". Second, in
situations where a large allocation was requested and there was
not a large chunk available, the allocation would enter a
live-lock condition where coalescing would never occur.
Switched the PageManager so that all allocations happen in
kernel space. This allows us to force memory-release operations
on the syscall path when we are out of memory and also put in
place a task_yield call which will allow coalescing to eventually
occur. Issue 44523 is suppose to fully resolve any of these
live-lock paths.

This code is currently unused, due to InitService not having the
payload address and the start_host_os IPL step being unimplemented.
For testing purposes the 'shutdown' call in initservice.C can be
changed to pass a non-zero base address (such as 256MB).

- Add task_end2 syscall to allow pthread_exit-like retval.
- Add/maintain task states.
- Create task parent/child tracking tree.
- Add task_detach function.
- Implement wait syscalls.
Make task_exec caller the parent of spawned task:
Previously the task_exec call caused a message to the
VFS task, which called task_create and returned the tid
in response to the message. This causes the parent of
the spawned task to appear to be the VFS task.
Modify task_exec / VFS handling to instead return the
entry point address on the message and have task_exec call
task_create directly itself.
