There is a scenario wherein if a PNOR ECC UE occurs when attempting to service a
page fault, the kernel will deadlock when it attempts to kill the task that
triggered the fault. This is due to the kill routine being called while holding
the VMM spinlock and then collecting a backtrace, which also performs
a nested acquire of the same spinlock. This fix inhibits invoking the
backtrace if the kill routine holds the VMM spinlock.

This commit fixes a bug wherein, if a task was pinned and then migrated to
master, a page fault to load any instructions after the migrate but before the
unpin, could cause the task to migrate away unexpectedly, causing a range of
symptoms such as not being able to find the master core.

If we hit a situation where we can't allocate a page of memory,
this will force a coalesce (defrag) a few times and then
eventually trigger other memory reclamation actions.
Also tweaked a few spots in the kernel to enhance debug:
- add more stops to look at errors (HB_BREAK_ON_ERROR)
- add more backtrace calls
- add a new debug flag to count the extra coalesce calls

- 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.
