This commit implements the POSIX setsockopt syscall so that user
programs may be able to configure sockets they have created.

This commit implements proper timeout handling for recv(). Previously,
the recv() syscall would yield the current process forver until data is
available to be read. Obviously, that is not the most ideal as it is not
uncommon for programs to try seeing if any data exists on the socket
before deferring to perform some other task until data arrives.
The basics of how this work is that we try reading data off of some
specified socket. However, if no data is present, we must wait for the
given timeout value before attempting to read again.
While this is pretty effective and works perfectly fine as of now, it
might be worth optimizing this later to allow that timeout period to be
somehow "interrupted" by data arriving at a socket so that the program
does not have to defer execution for the full wait-period.

This commit introduces the kernel-side implementation of setsockopt()
for setting options on a socket file descriptor. See POSIX

Implement mechanism that allows one to plot pixels on the screen with a
specific color at specific x/y coordinates.
Example:
--
struct gfx_point p = {
.x = 150,
.y = 200,
.color = GFX_GREEN
};
/* Draw green point at (150,200) */
gfx_plot_point(&ctx, &p);

This commit introduces libgfx which is a low-level graphics library
and does not know anything about windows, display architecture, etc.
