Create a RefCounted type and use it for Thread.
...
This should prevent me from actually creating 2 shared ptrs of
a single kernel object with their separate ref counts.

Add the ability to copy memory to non resident process.
...
Use/Test this by loading the user space elf from the kernel process
before it starts rather than as a part of the first thread.
This simplifies thread start a fair bit.

Move Processes and Threads to be stored in SharedPtr
...
Reference counting lets us pass these around a bit more easily.
SharedPtr was lightly tested using uint64_t in the main zion funcion.
Also add a sleep functionality instead of panicking. Functionally the
same right now since we don't preempt.

Move scheduler threads to a linked list implementation.
...
Removes the internal next ptr from the Thread class.
We avoid doing a memory operation when scheduling on yield because we
simply cycle the item to the back of the list.
