Seriously prioritise output.
...
Added a beep function to allow PC Speaker output.
This will require an edit to the current QEMU launchscript to get working.

Prioritise output before all else, just so we know when the kernel actually works.

Fix a silly issue with the Interrupts using bits instead of bytes when reading and writing ports.

NOTE: for every new successful build, start incrementing the SYNC_VERSION constants in kernel.h :D

Add some public-domain memory manipulation files as a stand-in for my AVX functions.
...
These are messy, but they let the kernel compile.

It's interrupt time, baby.
...
This should bring the kernel to a working state.
Don't forget that the interrupts.c file absolutely must be compiled with -mgeneral-regs-only.
All the other files absolutely must be compiled with -mavx2.
:)

Also added the missing memX functions needed for compilation.
Interrupts next, I do believe.

Finish basic memory management.
...
This won't compile, as it's missing the xAVX functions.
I have a sort-of implementation of them, but it's brutal.
5400 lines total.
For now, they can be substituted with the x functions (remove AVX) to compile the kernel.

The print file.
...
A whopper. Lots of printing functions, most of them internal.
No this doesn't mean actual physical printing, it's printf, etc.

It is to be split up in the future.
