e87eac9273 Userland: Add LibSystem and funnel all syscalls through it 
This achieves two things:

- Programs can now intentionally perform arbitrary syscalls by calling
  syscall(). This allows us to work on things like syscall fuzzing.

- It restricts the ability of userspace to make syscalls to a single
  4KB page of code. In order to call the kernel directly, an attacker
  must now locate this page and call through it.

1a08ac72ad LibC+Everywhere: Remove open_with_path_length() in favor of open() 
This API was a mostly gratuitous deviation from POSIX that gave up some
portability in exchange for avoiding the occasional strlen().

I don't think that was actually achieving anything valuable, so let's
just chill out and have the same open() API as everyone else. :^)
