Serial implementation Pt1
...
Serial testing with COM1 works - need to rework I/O to have it output
tho. That's next.

Changed I/O to be more generic.
...
instead of stuffing all of the i/o stuff into the "kio" library, i've
decided to rework i/o to be a generic handler that takes in a function
pointer for putc, and does the rest of the logic onto that pointer.
That way, you can pass any function that can take in characters and move
them to buffers.
I'll do a writeup on this at some point to document it.

Added tons of documentation
...
Still need to document a lot of functions, but I cleaned up and
explained a lot of the code via comments.

Loaded IDT!
...
Many code changes, many undocumented. Documentation and cleanup is next.
Fixed a lot of bugs related to IDT structure. Changed the IDT paradigm
to be dynamically written isntead of statically to account for nobits on
that section.
Also added a gdb remote debugger automatic script, for simplicity in
debugging.

Half-baked commit, but i added a struct type for the tss and allocated
...
some memory for it in bss. Also put some space in for the gdt in rodata.
Need to leave now, so this broken build goes to the repo!

Also added a printf for i/o.
