Updating the Simics level to get FSI fixes to allow multiple
chips to work. This also allows us to remove some previous
workarounds.
The new Simics build pulled in a different PNOR so needed to
disable some of the tests.
The new Simics build also modified some of the L3 objects so
changes were required to some debug tools.
Had to update the VENICE config since Ched rewired it to look
like MURANO/Tuleta.
Testing:
Verified 2-proc, 4-centaur MURANO config
Verified 2-proc, 4-centaur VENICE config

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).

I modified the settings for the periodics that run and keep free
memory available. This is needed for the VENICE config to not
fail with a OOM.

- Changed overall page table behavior to no longer use C bits
in page table entries. Instead, individual blocks mark
pages as dirty based on stores during page faults. Initially
all writable pages are marked read-only until the first store
to it. At that time the block gets an exception and changes
the permission on the page table entry to writable and marks
its own SPTE to dirty.
- Greatly reduced the number of tlbie's and page table accesses.
Accomplished this by:
* Skipping many of the page table manipulations, such as
LRU updates, when the PTE is invalid.
* Converting most of the previously general-case of
"Modifying a PTE" to specific cases such as "Resetting
the Reference Bit" and "Modifying the SW field".
- Fixed the LRU-flush algorithm so that it is O(n) instead of
O(n^2), where n = size of page table.

The P8 processor (in RFC02230 targeted for ISA 2.07) adds a
new SPR register HFSCR (Hypervisor Facility Status and Control
Register). This register allows the hypervisor to disable
access to some resources, such as floating point and VSX,
from a partition. The purpose of this is to save time in
saving the partition context when switching partitions.
Since we sometimes enable floating point instructions we need
to also enable the HFSCR[FP]. We could do this when enabling
floating point in the MSR, but the SPR does not exist in P7.
Instead we'll do it as-needed on the hw-thread the first time
it executes a FP instruction. The FP instruction will cause
the hype_fac_unavail exception and the exception handler will
set HFSCR appropriately.

- 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.
