91031346e5 Kernel: More signal handling improvements. 
Finally fixed the weird flaky crashing when resizing Terminal windows.
It was because we were dispatching a signal to "current" from the scheduler.
Yet another thing I dislike about even having a "current" process while
we're in the scheduler. Not sure yet how to fix this.

Let the signal handler's kernel stack be a kmalloc() allocation for now.
Once we can do allocation of consecutive physical pages in the supervisor
memory region, we can use that for all types of kernel stacks.

251293f2e1 Kernel: Block a signal from being dispatched again until handler returns. 
We don't handle nesting yet, but this is a step in the right direction.

beda478821 Kernel: Make syscalls that take a buffer size use ssize_t instead of size_t. 
Dealing with the unsigned overflow propagation here just seems unreasonably
error prone. Let's limit ourselves to 2GB buffer sizes instead.
