Kernel: Make syscalls that take a buffer size use ssize_t instead of size_t.
...

Kernel: Make BochsVGADevice a BlockDevice and support mmapping it.

Currently you can only mmap the entire framebuffer.
Using this when starting up the WindowServer gets us yet another step
closer towards it moving into userspace. :^)
