Drew Galbraith 23895b5c6c Spawn Processes using memory primitives rather than and elf loader.
This allows us to remove the temporary syscall for that style of process
spawn.

Drew Galbraith 4e278a4664 Make a KernelObject base class for all Capabilities. 2023-06-06 20:13:07 -07:00
Drew Galbraith 2e1357255c 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.

Drew Galbraith 3fee5ac9d7 Rework scheduler to store the current thread separately.
This works better with the sleep thread and lets us check state
transitions more easily.

Drew Galbraith 80d2bf1aaa 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.

Drew Galbraith 9f3ffbf5b4 Move Process to storing Threads in a linked list.
This should really be a vector or hashmap of some sort but this is fine
for now.

Drew Galbraith 5cab9f843e Move process list to a linked list.
Add basic iteration ability to the linked list.

Drew Galbraith 71196dc90f 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.
