More moving towards using signed types.

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.

Kernel: Add KResult and KResultOr<T> classes.
...
The idea here is to combine a potential syscall error code with an arbitrary
type in the case of success. I feel like this will end up much less error
prone than returning some arbitrary type that kinda sorta has bool semantics
(but sometimes not really) and passing the error through an out-param.
This patch only converts a few syscalls to using it. More to come.

It was very confusing that you had to open a FileDescriptor in order to stat

implement the stat() and lstat() syscalls.

Support resizing the Terminal app.
...
I set it up so that TIOCSWINSZ on a master PTY gets forwarded to the slave.
This feels intuitively right. Terminal can then use that to inform the shell
or whoever is inside the slave that the window size has changed.
TIOCSWINSZ also triggers the generation of a SIGWINCH signal. :^)
