239c0bd6a6 Kernel: Make block() and yield() automatically call Scheduler::yield(). 
This exposed some places we were accidentally doing a double yield().

e561ab1b0b Kernel+LibC: Add a simple create_thread() syscall. 
It takes two parameters, a function pointer for the entry function,
and a void* argument to be passed to that function on the new thread.

8501fdc6f5 Kernel: Don't add the colonel process' main thread to g_threads. 
This was causing the colonel to get scheduled when he wasn't needed.

60d25f0f4a Kernel: Introduce threads, and refactor everything in support of it. 
The scheduler now operates on threads, rather than on processes.
Each process has a main thread, and can have any number of additional
threads. The process exits when the main thread exits.

This patch doesn't actually spawn any additional threads, it merely
does all the plumbing needed to make it possible. :^)
